What is the point of having 2 graphics cards?
Some video cards, are able to bridge together and become a "virtual" one. Most people have two video cards for compatibility or multi-screening. I myself have a quad screen setup. They don't have to be SLI. I have 2 Nvidia cards and and ATI and they work together even though they are all different types of cards.





SLI is only used to bridge as far as I know.
Reply:Having more than one graphics card means more graphical power. Basically, you are combining the power of both cards.


Yes, they have to be SLI.
Reply:for now YES! SLI is the new way to reach the pinnicle of maximum gaming. SLI basically makes it to where each card focuses on only half of the screen. In the same way it doubles your graphics. For now the cards have to be the same make and model. You can't have an 8800 with 8600 GT side support. Get SLI, you can find decent SLI cards at www.tigerdirect.com . If you decide to get SLI, make sure the motherboard and the graphics cards are SLI ready.
Reply:The POint?? To brag about your system. No one needs 2 of the latest graphics cards, cureetly to play games, but then, Its nice to have games go at 140fps!
