This is quite natural, as having two graphics adapters allows for better performance. This is most relevant if you like to play computer games or if it is extremely important for you to have two or more monitors. It is with two video cards that two or more monitors will work in the best possible way.
If your motherboard already has an integrated video adapter, then there will be fewer problems with connecting a second video card, although you will lose in performance. The thing is, integrated graphics do not have much processing power. Usually such a "duet" is found on laptops, but on stationary computers it is rare. Otherwise, you will be using two full-fledged video cards and thus you will be able to achieve better performance and stability when working with multiple monitors.
Recommendations from IT Center SPb
Our company for subscription service of computers in St. Petersburg recommends purchasing two identical models of graphics adapters. This will reduce the setup time somewhat, as well as avoid other complications. However, you can use various device models - it all depends on your desire and capabilities.
For the simultaneous operation of two or more video cards, you will need a Windows operating system, version no worse than Vista. Previous versions do not support and it will not work to connect two video cards. Also, more than two video cards do not support Linux, and Windows has no problem with that.

Installing video cards on a personal computer

Install the video cards into the corresponding connectors on the motherboard. The main thing during their installation is not to damage the mounts and do not install them at the wrong angle. Connect both graphics adapters using the SLI bridge - it comes with video adapters that support this technology. The cable attaches to the top of the devices, literally making one whole graphics card out of the two.
The last thing is to download the latest drivers and install them on your computer. To do this, open your browser and enter the manufacturer of your video cards into the address bar of the browser. The first site on the list is the one that you need to find drivers. Go to the appropriate section on the website and download the software.
After installing the drivers, restart your computer. The video cards are ready to go.
