how to choose a graphics card

If you are buying or building a gaming PC, the graphics card is even more important than the CPU. and you must know how to choose a graphics card? Unfortunately, the process of figuring out when to buy a GPU can be daunting. There is a lot to consider for the configuration of the game you use, for the size of your PC case.

Below is the list of things to keep in mind when buying your next GPU. In this guide we will discuss How to Choose a Graphics Card?

Why is your graphics card important?

For many people, gaming is the most hardware-intensive task they would ask of their PC. It’s no of surprise that serious gamers spend many hours researching the latest GPU technology and update them. As GPUs accelerate, the game is designed to take advantage of the additional performance and motivates manufacturers to build even faster GPUs by continuing the cycle.

If you’re not prioritizing games, you may not care much about your GPU capabilities. That said, professional applications often make direct use of the GPU’s specialized processing capabilities, just in different ways. Examples include video editing, where a GPU can be used to accelerate applications such as video encoding, 3D rendering, and computer aided design / manufacturing (CAD / CAM) such as AutoCAD. All of these programs benefit from the additional processing power of a GPU, although they benefit most from a GPU designed specifically with these applications in mind.

Therefore choosing a GPU is an important and depends How will you use it?


The gaming industry has made an important contribution to the development of GPU technology. Today’s PC games are more realistic and complex than ever, and the reason for the increased performance of modern GPUs is both the response from gamers looking for more complex and better-looking games.

Simply put, if you’re building a gaming PC, the GPU will be your biggest purchase. Other components can affect performance too, such as CPU, storage, and RAM, but the GPU has the most direct connection to what you see when you play games on the screen.

However, there are many different types of games and not all of them demand the most powerful GPUs on the market. That’s why it’s important to read the required, recommended, and optimal specs for your game to make sure you’re getting the right GPU.

Video and Professional Applications

People who use their PCs for complex tasks like 3D rendering, game development, and video editing also benefit from faster GPUs. High-end applications like AutoCAD and Adobe Premiere Pro can use GPUs to speed up processing for faster and more efficient work.

That is why there is an entire segment of GPUs designed specifically for professionals. These workstation GPUs are optimized for these applications and their drivers are certified to be stable and reliable when performing these tasks. The most expensive GPU is not always “better”, and it is important to choose a GPU based on how you plan to use it, especially not price.

In this guide, we will focus on the more mainstream and gaming-centric graphics card. If you need a GPU to run business applications, you will be looking for the best options in the general consumer GPU market.

If you’re not demanding commercial games or applications that can use a GPU to speed things up, you don’t have to spend as much money on your graphics card.

The graphics capabilities built into your system’s CPU are probably sufficient and you probably don’t need a separate GPU.

Quick Tips on How to Choose a Graphics Card

Save some money for the CPU

You no need to spend all the money on graphics and skip the processor. If you do this, your system may score well as per spec, but it won’t in actual game (due to the lower minimum frame rate).

Match the resolution of your monitor

Many conventional cards are sufficient to play at 1080p resolution between 30 and 60 fps, but you will need a higher resolution card for 4K resolution with higher in-game settings on the most demanding titles.

Consider your update frequency

You will need a powerful card and processor If your monitor has triple-digit refresh rates, to reach its full potential. Alternatively, if your monitor maxes out at 60Hz and 1080p, it doesn’t make sense to pay more for a powerful card that pushes pixels faster than your screen.

Do you have enough power and space?

Make sure there is enough space in your case for the card you are considering and that your power supply has the correct type of power connector (up to two 8-pin PCIe depending on the card) to spare. There are enough watts.

Check the MSRP before buying

A good way to know if you are getting a deal is to check the introductory price or MSRP of that card before purchasing.

Don’t get double cards, they are not worth it

Gaming support for multi-card SLI or Crossfire setups has been running out for years. Get the best individual card you can afford. Adding a second card is often more troublesome than it’s worth.

Don’t rely on overclocking to promote serious performance

If you need much better performance, then you must buy a more powerful card. Graphics cards typically don’t have a large amount of overclocking headroom, typically only 5-10%.

How to Choose a Graphics Card?

Graphics card memory amount

Get a card with at least 4GB and preferably 6GB or more for 1080p gaming. If you play with all the settings or install a high resolution texture pack, you will need more memory. And it is ideal if you play at a higher resolution, such as 4K, 8GB or more.

Farm Factor

You should make sure you have room for your card in its case. Look at the length, height, and thickness. Graphics cards usually comes in half-height (slim), single slot, dual slot, and also in triple slot flavors. Most gaming focused cards will be full height and will occupy two expansion slots. Although a card technically only takes up one or two slots in your case, if you have a larger heat sink and fan shroud, you can block an adjacent slot.

Thermal Design Power

Thermal Design Power or TDP is a measure of heat dissipation, but it also gives you an estimate of how many watts you will need to run your card in the standard configuration. If you are running a 400 watt power supply unit (also called PSU) with an overclocked 95 watt CPU and if you want to add a GTX 1080 Ti (which has a 250 watt TDP), then you need a power supply upgrade. . . Typically a 600W power supply supports all powerful graphics cards and 800W is sufficient for any overclocked GPU.

Power connectors

The most serious gaming cards consume more than the maximum standard of 75W provided by the PCIe x16 slot. These cards require connections to complementary PCIe power connectors that come in 6-pin and 8-pin varieties. Some cards have one of these connectors, some two- and six- and eight-pin ports may exist on the same card. If your PSU does not have the supplemental connectors you need, you want to upgrade; Adapters that make power from a pair of SATA or Molex connectors are not recommended as a long-term solution.


Some monitors have HDMI, some use DisplayPort, and some very old units only have DVI. Make sure the card you buy is the necessary connector for your monitor (s), so you don’t have to buy an adapter, or possibly a new display (unless you want to).

Clock speed

Cards with similar GPUs (for example, the Nvidia GTX 1060), some will be overclocked by the manufacturer at slightly higher speeds, which can make a slight difference in frame rate. However, clock speed is not everything, as the number of cores and architecture must be taken into consideration.


TFLOPS, also called trillions of floating point operations per second, is the maximum theoretical performance of a GPU. (This can also be expressed as billions of GFLOPS, or FLOPS.) The core count multiplied by the clock speed, multiplied by two (for FMA or fused multilevel instructions), will give you TOOPS for the GPU. Comparing within the same architecture, TFLOPS usually tells you how fast it compares to another on one chip. Comparisons between architectures (for example, AMD Navi 10 vs Nvidia Turing Tu 106, or AMD Navi 10 vs AMD Vega 10) are less helpful.

Memory Speed ​​/ Bandwidth

Like higher clock speeds, faster memory can make one card faster than another. The GTX 1650 GDDR6, for example, is about 15% faster than the GTX 1650 GDDR5, all thanks to higher memory bandwidth.
