It depends on what resolution you're running and what game your playing. Something like COD will scale quite well because it isn't limited by the cpu. Other games would become cpu limited like Far Cry 2, but if you're using a triplehead setup or a 30" then you'll likely run out of vram before you can fully utilize all 3 cards. There are scenarios where the processor could easily be holding them back though.
