Just thought Id mention that Ive installed Crysis on my MBP (2.6ghz, 4GB ram and Geforce 8800 256MB Video card) and Im able to play with all of the settings on high, AA off and 1024 x 768 resolution. So far its not too bad and Im thinking of pumping up the resolution a notch or two to see how much I can get away with.

Anyways, if youre thinking of trying Crysis, give it a go.
