Ther Major custom computing guide to graphics cards

For gaming PCs and workstations, the graphics card is a key element in your PC build.

A graphics card, also known as a video card or GPU (graphics processing unit), is a hardware component that is responsible for rendering and displaying the images on a computer's screen. It is a separate component from the motherboard and CPU, and is typically located on the computer's PCIe (Peripheral Component Interconnect Express) bus.

When choosing a graphics card, there are several factors to consider, such as the type of GPU, the amount of memory (VRAM), the available ports and connectors, and the overall performance and power consumption. Here are some things to keep in mind when choosing a graphics card:


The GPU is the most important part of the graphics card and is responsible for the majority of the rendering and processing tasks. Choose a GPU from a reputable manufacturer, such as NVIDIA or AMD, that offers good performance and support for the latest graphics technologies.


VRAM (video random-access memory) is a type of memory that is specifically used by the graphics card to store the data and instructions for rendering images. The amount of VRAM on a graphics card can affect its performance, especially when playing games or running resource-intensive applications. Look for a graphics card with at least 4GB of VRAM, but more is better if you can afford it.

Ports and connectors:

The graphics card has various ports and connectors for attaching a display, such as HDMI, DisplayPort, and DVI. Make sure the graphics card has the right types of ports and enough of them to support the number of displays you want to use. Some graphics cards also have additional ports and connectors, such as USB and Ethernet, which can be useful for connecting other peripherals.


The performance of a graphics card is determined by a combination of factors, including the GPU, VRAM, and the design of the card itself. Look for a graphics card that offers good performance for the applications and games you want to run. Keep in mind that more powerful graphics cards typically consume more power and generate more heat, so make sure your system can handle it.

Power consumption:

The power consumption of a graphics card is determined by its performance and design. More powerful graphics cards typically consume more power, which can put a strain on your power supply and increase your electricity bill. Check the power requirements of the graphics card and make sure your power supply can handle it.


Graphics cards can range in price from around £50 to over £2,000, depending on the performance and features. Consider how much you are willing to spend and choose a graphics card that offers the performance and features you need at a price that fits your budget.

For a gaming PC, you should look at assigning approx. 1/3 of your budget to the graphics card.

Should I choose NVIDIA or AMD?

Both NVIDIA and AMD are leading manufacturers of GPUs (graphics processing units), which are the main components of a graphics card. Choosing between the two largely comes down to personal preference and the specific needs of your system.

In general, NVIDIA GPUs tend to offer better performance and support for newer technologies, such as ray tracing and AI-powered rendering. They also have a wider range of products at different price points, from budget-friendly options to high-end graphics cards for gaming and professional applications.

On the other hand, AMD GPUs tend to offer good value for the price and often have more affordable options in the mid-range market. They also have strong support for multi-GPU configurations, which can be useful for users who want to run multiple graphics cards in their system.

Ultimately, the best choice for you will depend on your specific needs and budget. It's a good idea to research and compare the available options from both NVIDIA and AMD to see which one offers the features and performance you need at a price that fits your budget. You can also read reviews and consult with other users to get their opinions and experiences with the different GPUs.
