Sadly SLI doesnt support all games out there. is it one third that is supported? Forget the figure...
Any case, the ATI crossfire wont have that problem. Crossfire will support ALL games and have multiple possible configurations, whereas SLI FORCES you to have identical cards with identical BIOS.
ATI is even releasing a card soon, R520, that is (allegedly) more powerful than two 6800U in SLI mode. Might be rumours, but the crossfire thing still sounds way more potent and flexible.
