I don't see crysis 2 being too much more demanding than the original unless full destructibility of objects is introduced unless they don't optimize it well in which case it will not likely be maxed out by a single graphics card (non sli) until 3-4 generations of cards later. I'm really hoping that it will run on the same hardware as crysis 1 and not in the comparison some made between farcry 1 and crysis which was if you can run farcry maxed out you can run crysis on low
