Come on man> Your system should be plenty stout to play crysis @ Very High, just not with AA enabled. I have a budget system with a 19" Monitor and i am able to play Crysis and Warhead @ Very high with motion blur maxed out no AA @ 1440X900. But you should have upgraded to 4gb of ram especially when you have 64bit Vista. Go for a GTX260 or a 4870 to add @ very high settings some AA.
