I have two graphics cards(both geforce), one is a 6800 gs (old one) and I now use a 8600gt. I have discovered that both support something called SLI. I did some research, but couldn't understand one thing: can I SLI these two cards together? If I do, will I get a benefit?
Also, if I get a 8800, can I SLI that with my 8600?
