GPU Buying Guide: How To Choose The Right Graphics Card

Insufficient GPU power will affect the performance and lead to poor visual experience during games, photo and video editing and other visual tasks. If you don’t know where to start, our graphics card buying guide will help you make the right decisions when it comes to choosing your next graphics card and taking control of your PC’s graphics performance.

Along with your computer’s processor (CPU), the graphics processing unit (GPU) has the greatest influence on your computer’s performance. This is because the GPU processes the data from the CPU and renders it visually on the screen. However, knowing all the details of knowing when to upgrade your GPU and choosing the right graphics card for your needs can be confusing.

Why you should upgrade your graphics card

More than any other component of a PC, the GPU is responsible for the quality of the graphics or visuals that appear on the screen. In the beginning, processors were responsible for both processing and rendering graphics, but nowadays virtually every computer on the market includes some kind of graphics card.

As graphics cards age, they become less able to keep up with the latest games, streaming, and software. While they don’t actually degrade, your 5-year-old graphics card may not support the latest video editing software or stream 4K video without stuttering. Or, it may have a hard time presenting your brand new video game the way you want.

When you plan to upgrade your graphics card, you should really think about how you use your computer. For example, if you mostly use your gaming PC and newer games don’t run at a constant 60 frames per second (fps) then that’s a good sign that you need to upgrade.

Potential bottlenecks

Make sure your GPU is not causing CPU bottlenecks. This happens when the CPU is generating more frames per second than the GPU can handle, which can lead to screen stuttering. If this scenario affects your computer’s performance, most likely you need to update your graphics card.

Why does your graphics card matter?

For many people, gaming is the most hardware-intensive task you can ask your computer to do. So it’s no surprise that serious gamers spend hours researching the latest GPU technology and frequently update their GPUs frequently. As GPUs become faster, games are designed to take advantage of the extra performance, forcing manufacturers to create even faster GPUs while continuing the cycle.

If you don’t prioritize gaming, you may not care so much about your GPU’s capabilities. That said, professional applications often take advantage of the GPU’s special processing capabilities directly, just in different ways. Examples include video editing, where the GPU can be used to speed up processes such as video encoding, 3D rendering, and computer-aided design / manufacturing (CAD / CAM) applications such as AutoCAD. All of these programs use the extra processing power of the GPU, although they benefit most from GPUs designed specifically for these applications.

Choosing a GPU is therefore an important part of building, purchasing, or upgrading your computer. As with any PC component, the first question to ask yourself when choosing a graphics card is how will you use it?


The gaming industry has played a key role in the evolution of GPU technology. Today’s PC games are more realistic and complex than ever before, and the rising performance of modern GPUs is both one reason and a response to gamers demanding better looking and more complex games.

Simply put, if you’re building a computer to play games, the GPU will be your number one purchase. Other components can affect performance as well, such as CPU, storage, and RAM, but the GPU has the most direct connection to what you see on the screen while you play.

However, there are many different types of games out there, and not all of them require the most powerful GPU on the market. Therefore, it is important to review the required, recommended, and optimal game specs to ensure you are getting the right graphics card.

Buying the best GPU you can afford is a good way to secure your version in the future and keep it ready to play popular games that have yet to be released. That said, if you know exactly what games you want to play, doing a little research into the ideal GPU to run this title is a great way to start the purchasing process.

Video and professional applications

Those who use their computers for complex tasks such as 3D rendering, game development, and video editing also benefit from faster graphics processors. Advanced applications such as AutoCAD and Adobe Premiere Pro can use graphics processors for faster processing and a faster and more efficient workflow.

Therefore, there is a whole segment of GPUs designed specifically for professionals. These workstation graphics processors are optimized for these applications, and their drivers are certified to be stable and reliable in performing these operations. Professional-grade graphics cards can be extremely powerful and are often more expensive than even high-end gaming GPUs, but since they aren’t specifically designed for gaming tasks, they’re likely not ideal for gaming PCs. Therefore, the most expensive GPU is not always “better”, and it is important to choose a GPU based on how you intend to use it, not just on price.

Integrated vs discrete GPUs

Most modern processors have integrated graphics, which are essentially graphics processors built into the processor itself or otherwise closely related to the processor. These integrated graphics tend to be lower-performance options, providing enough power to run your operating system and run web browsers, email clients, productivity apps, and other routine software, but they don’t do anything more than regular (or older) games. This changes quickly as processors get more powerful, but for now, if you want to play games, a separate (or discrete) GPU is probably your best bet.

Standalone GPUs range from relatively inexpensive, entry-level options to incredibly powerful GPUs that alone can cost well over £ 400,000. You can purchase discrete GPUs as part of off-the-shelf systems, for a PC you build yourself, or to upgrade an older GPU.
