It's some time later, but Crysis runs beautifully on my Phenom rig.
1680x1050, all in-game options on "high", 4xAA, 16xAF, GCAA, MSTA, vsync, tb- all via driver control panel.
Runs fine. Everyonce in a while when entering a new large area it'll stutter for a second or two while stuff is loaded but that's about it. Does not hitch up or stutter during intense firefights or what not. It never used to perform so awesome untill these latest drivers. Not sure what they did, but I like it.
