I was watching this 3-way SLI review and was interested to see how much of an improvement it would make in Crysis but I am quite surprised that the framerate never got above 40fps no matter what they did 
So if a Core 2 Extreme QX6850 and three 8800Ultra's can't even get >40fps at 1280x800 what the hell is the limiting factor in this game?
