And how does this show us, that nVidia is better?
Since you posted your frequencies:
ATI 9550 GPU: 250 MHz
ATI 9550 Memory: 200MHz
The 9550 is something very useful for running Office, nothing else. Even when it was released. That has nothing to do with ATI-Quality, though, or giving a reasonable basis to say that Crysis doesn't run with ATI-cards.
