Choosing a graphics card is much more important than selecting a processor, especially when it comes to building a powerful gaming computer or a device for designers, photographers, or software developers. There are hundreds of graphics cards from dozens of manufacturers, but the most popular are NVIDIA, AMD, and Intel. NVIDIA graphics cards lead the market, but even with this brand's gaming graphics cards, maximum performance can only be achieved if all components are compatible. Special attention should be paid to the compatibility of the graphics card and the motherboard.
Key PC Parameters When Choosing a Graphics Card
A graphics card processes data and outputs graphics, photos, and videos to the screen. Without a good graphics card, it's impossible to process high-throughput videos or play modern games with impressive graphics. A new graphics card for a computer must meet the specifications of the processor and motherboard. Otherwise, even if the graphics card can be installed, you won't be able to take advantage of all the benefits of the new graphics processor. When purchasing a graphics card, consider the following:
- availability of the necessary ports and connection requirements;
- performance;
- adapter sizes;
- power supply features;
- motherboard connectors.
Some graphics cards take up two or three slots due to massive cooling. Make sure you have enough free slots on your motherboard and case.
If you choose a high-performance card and install it on a weak processor and an outdated motherboard, you won't see significant changes in PC performance. Videos and games may lag, sound can fall behind the video stream, and large graphic files may fail to load at all.
Motherboards with PCI Express x16 Connectors
For the last 15 years, motherboards have been made with PCI Express and its various versions, with two, four, and more channels (x2, x4, etc.). The most common high-performance expansion slot is the PCI-Express port with 16 channels and a bandwidth of 40 Gbps. Such a connector is present in almost any modern motherboard. A graphics card for a computer needs to have the same port - this way, there will be no compatibility issues.
Other versions of PCI Express differ from each other not by the type of connector, but by bandwidth. Therefore, practically any computer not older than 15 years will be suitable for a graphics card with a PCI Express port.
AGP Connector on the Motherboard
Some PCs still have outdated AGP connectors. You need to compare the photo of the future graphics card ports with the installed motherboard. To do this, simply open the computer case and examine the motherboard or find its specifications on the manufacturer's official website.
Often, it is not possible to select a suitable graphics card, so replacing the motherboard with a modern version is required. In older PCs, motherboards with other connectors may be found, so before purchasing a graphics card, make sure it is compatible with the board. Otherwise, you will not be able to connect the graphics card.
