simply put.... no.
From what people saying is that its more of a GPU when maxing out in games.
With my Rig, i get about 20-30 FPS in the beginning of the game, all on HIGH one DX9 on XP.
While on Vista, i only get those FPS with mostly Medium, and some HIGH.
To consider running on MAX, would be everything on Very High, on DX10, and with the max AA on, and the FPS will stay above 60 FPS.
So if the 8800GT only gets those FPS, then i dont think the 9600GT can max out the Crysis.
