In case you're worried about how well Crysis will perform on your new rig, it looks like it runs pretty smoothly at 2048x1536 assuming you have a Core 2 Duo and (single) 8800GTX running on Vista.
In an earlier article, it was reported that Crysis was running at 60+ fps for most of the time at CES 2007. In this new article, Jack Mamais tells techspot that the game is running at a resolution of 2048x1536.
