Single vs SLI Video Cards

Do you need one video card, or you need more than one? Since AMD and NVidia release technology that permits the use of more than PCI express card on single computer. Pc gamers and other computer enthusiasts are building super powerful gaming rigs. The question is, do you really need these types of computers?

For multimedia professionals who works on and deals with graphics and animations every day, the difference that multiple PCI express graphics cards is really felt. Apps used for processing images and animations are seamless and looks better and loads faster. But if you are an average user, that only uses your computer for word processing, emailing, social media, video streaming or watching and a little bit of image onboard or low-profile graphics card will do.

Currently, there are only two types of video cards that supports multiple PCI graphics cards. It can be hooked 2 or 4 GPUs per batch in one computer. These two are the SLI and the Crossfire video cards.

SLI stands for Scalable Link Interface. It was manufactured by Nvidia, it was introduced by the company in 2004. Before only two SLI cards can be used together in one PC. But it evolved and now there is quad SLI video cards that can support 4 SLI cards in one computer. For great GPU comparison you can visit the site in the link.

Shortly after the SLI release of Nvidia, its competitor ATI then but AMD now also came up with their own version of multiple cards platform the AMD Crossfire. It was introduced in 2005.  Like the SLI it can support up to four graphics cards in one single computer.

Compatibility issues with motherboard will limit you from running multiple cards in one computer. Only specific motherboards can support SLI and Crossfire video cards and also it cannot be mixed and matched. AMD Crossfire is more adaptable and can be used in most Intel motherboards that have at least two PCI express cards. You can check out this site for great comparison review and compatibility issues.
