A Complete Guide To Buy The Right Graphics Card (GPU) For your PC


Need help buying graphics cards? Read this article to combat that problem and get the right card for your needs!

Gaming graphics cards have advanced in recent years, but choosing the right one can still be challenging.

The first choice you’ve got to make is what kind of card will work with your system. AMD or NVIDIA? What about the amount of RAM? Resolution? Refresh rate?

Which one would be best for you? You may already know which well-known company you're leaning towards, but here's a quick rundown on how each option might work for full compatibility.

AMD offers slightly lower performance than NVIDIA; however, these cards are cheaper and come with built-in display ports (or DVI), perfect if you plan on staying in the game.

For those who want decently priced hardware that doesn't skip out on design, we recommend NVIDIA GPUs. The best way to take gaming to the next level is by getting a 4k graphics card.

If you are looking for a graphics card, the following article can help you choose the right one. We talk about some of the factors that need to be taken into account when purchasing a GPU.

AMD or NVIDIA: Which One To Choose?


When you’re looking for a graphics card, there are many choices to make before you buy: budget, performance, and compatibility with your current hardware can all be big deciding factors.

"AMD graphics cards have been the go-to staple of gaming computers for PC gamers since they were originally created.

NVIDIA entered the market with high hopes, but AMD had already built an impressive reputation and up until now NVIDIA hadn't surpassed them in popularity."

"With this digital dichotomy shifting towards a more virtualized landscape, it's important to know what your needs are going into one of these systems.

The goal is not just to be able to perform -either by playing games or coding-but also for your computer system to live as long as possible despite ever-changing trends in computing."

"Before you buy a graphics card, it's important to make sure that it is compatible with your system."

If you're purchasing an NVIDIA graphics card for an AMD motherboard then there are some complications."

Some newer GPUs require a PCI-E x 16 slot but many older computers only have a PCI slot available," though this doesn't mean they won't work."

NVIDIA's top-end RTX cards are considered the best graphics card on the market, which is why they're always in high demand.

NVIDIA's RTX cards are the best graphics cards in 2021. Their top of the line products have been ranked at number one for many years, even after being released to public consumption around five months ago.

The NVIDIA company has always had a reputation as a high-end provider with powerful and innovative technology.

Which is unparalleled by other leading competitors who serve different markets or offer lower performance levels when it comes to their GPUs (graphics processing units).

This could be why demand for these higher end devices remains so high; they're still considered better than what most people can get elsewhere on any given day.

The popularity of AMD graphics cards has been steadily climbing in the last decade. The main reason behind this is because for most users, they offer better value than Nvidia products.

The most important aspects to check when buying a Graphics card for your PC are: its power supply requirements, the number of video memory it has and the maximum resolution that you will be using.

Considering Type Of Games To Be Played?


I am a gamer and I know how important it is to find the right GPU for your gaming needs.

There are many different types of games that gamers play, so you need to think about which type of games you are going to be playing on your new GPU before buying one.

For example, if you're going to be playing lots of first-person shooter games then you should get an AMD Radeon 6900 XT DirectX or NVIDIA GeForce RTX 3090 because they have great FPS rates.

If you want something with longer battery life and mainly use laptop computers for work purposes, then go with Intel HD Graphics 620 as they have better energy efficiency than other GPUs do.

Graphics cards are essential components of gaming computers that help them output images and videos in real time.

If you want to make sure that your computer has the best possible performance, then you need to find out what type of video card will work with OS and hardware specifications like CPU speed, memory size, motherboard design etc.

AMD and Nvidia Graphics Card Differences?


Nvidia graphics chipsets are more expensive to manufacture so you'll find their video card models priced higher when compared to similar performing AMD counterparts.

This doesn't mean that all Nividia graphics cards cost more though; some lower end models like the GeForce GT 750 or GTX 1050 Ti can actually be slightly cheaper then a comparable model from AMD's Radeon RX series.

You should also note that newer games usually need at least DirectX 12 capabilities if not Windows Premium Edition which means having an NVIDIA GPU might force your computer into upgrade mode.

The GeForce series graphics cards from Nvidia are more suitable for higher-end workstations and gaming rigs that need to render animations.

Video editing software or play games at a high resolution with increased texture quality where the performance demands should be met by your graphics card's GPU rather than relying on computational power of your CPU.

This is because these models will have over two times as many CUDA cores than their AMD counterparts which means they'll offer a better rendering experience when it comes to design applications like Adobe Premiere Pro CC, AutoCAD, or Blender Cycles Render Engine.

Considering Display Resolution


When it comes to PC games, the resolution you play them at is important. The higher your monitor's resolution, the more powerful graphics card that will be needed in order for it to run smoothly.

For example if you are playing a game from 4K on a standard 1080p screen (which has half of its pixels), then an average level low-end GPU would suffice but when played on 4k with twice as many pixels-an ultra high end and expensive cards might just barely cut it!

Therefore, if you are intending to play games at the highest resolutions that your graphics card supports (such as 3440 x 1440), then go for more than one GTX 2080Ti.

But if all you will be doing is watching Netflix, surfing Reddit or checking email – don't worry about any of this stuff! A decent CPU paired with integrated Graphics Card should do fine for such tasks.

Considering Monitor Refresh Rate

The higher the refresh rate, the quicker a monitor can display new images.

After years of progression in video processing hardware and software programming techniques, monitors have evolved from 60Hz to 90 Hz to 120Hz or 144Hz (in some cases).

If you are using your computer for gaming or other graphically intense work then we recommend that you use a screen with at least 240 Hz refresh rate as anything less will result in visible tearing on displays which is not good if you intend to game!

How many frames per second does your monitor support? If you are not sure, check the settings on your computer screen.

As resolutions and refresh rates keep improving for monitors with each generation of technology.

It is important to make sure that any future graphics card purchase can help push pixels through at a high enough frequency so they do not appear blurry or jagged in motion.

Compatibility With Your Power Supply

You have to make sure that the power supply you are using is up for the task.

It’s not a good idea to upgrade your graphics card and then find out that your spare PSU can’t keep it going, or worse still blow up in spectacular fashion due to inadequate power!

So we recommend upgrading both at once instead of trying to do so one by one as this will lead to compatibility issues later on down the line.

In order for an ATX system tower case Graphics Card (GPU) or video card compatible with it, you need: -a motherboard with enough PCI-Express slots available; -power cables from computer's power supply able (in most cases).

The size of video cards is measured in inches, with the most common being 12.

If you are not sure of your power supply's wattage or need more than 300W then it is best to replace them rather than risking a meltdown.

Thermal Design Power (TDP)

Thermal Design Power (TDP)

The power supply is what the GPU calls home and when it's not up to par, your graphics card will run like a clunker.

Graphics cards can be expensive, so that means you'll want to make sure you have an efficient enough PSU for them before investing in one because if there isn't enough juice then this bad boy won’t work at all.

In order for GPUs (graphics processing units) to function properly they need two things: sufficient cooling & reliable performance from their central processor or CPU.

If either of these are compromised by insufficient wattage/cooling respectively then expect some serious graphical glitches.

The graphics card's power and heat depend on the TDP. The higher this number is, the more wattage it requires to operate properly, with a corresponding rise in temperature levels.

In desktops as well as laptops where space constraints are important due to heating issues, thermals can become an issue of high priority for manufacturers or gamers alike because they want their system running at peak performance without overheating over time.

So understanding what kind of GPU you have available before purchase becomes critical when deciding which equipment will work best together from both design aspects (size) and thermal specifications that dictate how much room your computer needs between its different components given various processing loads.

Technology has advanced so much that the power and thermal draw of a GPU is now becoming an issue. But you can keep your computer running smoothly if you buy a powerful, yet efficient card like the NVIDIA GeForce GTX 2080 Ti.

This is important to know before purchasing a graphics card because you want your system running as smoothly for as long as possible without needing expensive hardware upgrades in order to keep up with new games that demand more from the GPU over time.



If you are considering the card for use in a computer that has 16GB of memory, and your graphics card needs more than 12 GB of RAM to run games smoothly, then it’s not compatible.

A video adapter must have enough room on its own to access all the system memory without conflict with other components such as the CPU or motherboard chipset.

Your best bet is to check before purchase if your PC can support any potential upgrades by looking at how much space there is inside your machine between components when removed from their housing (especially if you plan on upgrading).

Although VRAM is important, the amount of bandwidth your GPU provides may be even more significant. The data written to and read from this memory needs a lot of space on the bus between graphics card and display device which can become restrictive when running multiple displays or high-definition screens with higher resolutions.

If you are considering getting a new discrete GPU for one reason or another (most notably, upgrading), it's always worth looking at both aspects before making a purchase!

You don’t have to worry about the VRAM, as long as you buy a powerful enough card for the games that you want to play. You can see this in action with how fast memory bandwidth (or raw data throughput) is important on GPUs--the faster they access information and display it on-screen, the better performance will be across different tasks which require heavy graphical processing power like gaming or video rendering workflows.

RAM capacity measures just one way where CPUs are typically stronger than GPUs these days; however even if say that CPU capability scales up much higher due to architectural improvements over time compared against what's possible from NVIDIA & AMD respectively while maintaining comparable cost and power consumption, RAM is just one of many factors that will come into play.



The most important factor in choosing a graphics card is the interface. The video card must match up with the computer's motherboard, not just its processor type or DirectX version.

Otherwise, you will not get good performance and smooth playback of high-definition video; it could even cause system crashes if your PC can't handle it.

If your computer has an AGP slot for installing a new video card, then use that instead of PCI slots on newer motherboards because there are fewer limitations when using AGP technology.

PCIe slots are the new power outlet. They’re everywhere, and there is always a shortage of them for your needs! If you want to plug in something shiny like an expensive graphics card or other component that requires its own slot, you need to be sure it will fit into the available space on your motherboard- specifically any unused PCIe Slots.

You also shouldn't forget about all those pesky cables going from one device to another; GPU's usually come with more than just enough cord length so don't let their cable management skills away what fits best inside your case as well!

Graphics card compatibility is usually determined by the PCI Express slot on your motherboard, because graphics cards that require their own slots can't be used in a system with only one or two available.

In general, PCIe x16/x32 are reserved for video cards while other devices (such as sound and network) use lower-speed physical connections such as PCI or AGP.

So if you want to install an expensive graphics card like this NVIDIA GeForce GTX 1080 Ti 11GB Graphics Card which I just happen to have handy next to me here at my desk, then make sure you're going to have enough space!

You also shouldn't forget about all those pesky cables going from one device to another; GPU's usually come with more than just enough cord to power them.

One of the most important cables you'll need is called a "dual-link DVI connector" or sometimes just an HDMI cable (depending on what type of graphics card and monitor you have) to connect your video card with your display device, otherwise everything will be blurry!



There is no doubt that the GPU offers a lot of processing power. But, it can not do anything without being connected to other parts such as a motherboard and display or multiple displays for functionality purposes.

There are three main connections used by modern day computer monitors which include DVI (Digital Visual Interface), HDMI (High-Definition Multimedia Interface) and DisplayPort with VGA available on some computers but disappearing quickly into obscurity - an older legacy connection in comparison to what’s now offered today though still possible if needed.

If you want to get the most out of your PC, then make sure that it has enough output connections for all the monitors. Take note; graphics cards can have different types of connectors so be careful when shopping around or else you might not end up with a monitor which is compatible!

The graphics card needs to have at least one DVI, HDMI or DisplayPort connector for a video monitor.

PCs with two monitors will need a graphics card that has this many connectors: A dual-head graphics card will need at least six outputs (two DVI ports and four displayports) while three of these ports are required on the minimum for triple head setups.

The same setup applies if you want to use more than three displays but the number of cables may vary depending on how they’re set up and so it's worth doing your research before buying!

Multi GPU


If you run a game that is too demanding on your graphics card, it may not be able to keep up with the speed of data coming in. This can cause lag and glitches that make playing difficult or impossible.

One option for avoiding this problem is getting more than one graphics card—which will work together just like they would if there were two separate computers working at once!

When deciding which cards to use, consider whether you want AMD’s Crossfire or Nvidia's SLI tech; both have their own pros and cons when compared side-by-side: "Nvidia offers an easier installation process because all necessary cabling comes from the motherboard."

However, some games are optimized better for AMD GPUs (and vice versa). And now ,Nvidia supports DirectX 12, even if AMD cards are typically more powerful.

Though SLI and Crossfire setups are not as common now, there is still a way to get that much-sought after graphics power.

"You should buy Nvidia GPU chips if you want to enjoy a high-quality gaming experience. These graphics cards are designed with dedicated video memory, which means that they're able to produce more frames per second than most of their competitors' products can."

If you want wide usability of SLI or crossfire, then it’ll be better if you go with older GPU models like 1060 GTX in order to avoid missing out on newer technologies such as ray tracing should they become more mainstream later down the line once new consoles come out soon enough.

Integrated vs. Discrete Graphics Cards (GPUs)


A video card is either an integrated graphics processor (IGP) or a discrete graphics processing unit (GPU). Most modern computers use IGP chips as they are cheaper and more than enough to power the graphical needs of your average computer.

Discrete GPUs, on the other hand, have their own dedicated memory chip for storing image data and often cost less to purchase but require additional cooling when used in conjunction with high-end CPUs.

If you are looking for gaming performance then it's advisable to go for a GPU with at least two gigabytes of GDDR Memory such as AMD Radeon R Vega 64 Air Cooled Edition Graphics Card - 12GB HBM Memory’s which will provide some much-needed breathing room should things start running a little too hot.

And if you are up to date on your graphics card compatibility, then the chances of a hardware failure is unlikely as they'll be replaced before it's required.

The best way to play your favorite video games is with a dedicated GPU. Integrated graphics in CPUs are not powerful enough for anything more than casual or older games (unless they happen to be very lightweight).

As long as you're satisfied with running web browsers and productivity apps, then an integrated graphics chip will do just fine!

What is Ray-tracing in Graphics Cards?

Ray tracing

Ray tracing technology has been around for years, but recent advancements in tech have seen it make a comeback. Raytracing is responsible for more realistic lighting effects that accurately simulate how light behaves in the real world-- much like what you'd see on TV or movies.

It allows for high-quality graphics without the need to rely on powerful hardware. This is why more and more games are incorporating ray tracing into their design, including Battlefield V-- which has seen major graphical improvements thanks to this tech!

Raytracing can also be used in other applications like architectural renderings or video editing software as well. It's a game-changer when it comes to realistic graphics, so make sure you're checking compatibility before buying your next GPU!

The idea of ray-tracing is not new. But in computer graphics and animation, it's a fairly recent development that has taken off as the next step for 3D rendering despite its complex process.

Ray tracing calculates the color of pixels by following the light across objects through all types of reflections - from one object to another or even back to itself.

The concept behind using this technique may be convoluted but what can you say? It just might produce some pretty amazing results when used correctly with advances in processors today!
