Batman: Arkham Asylum
Batman: Arkham Asylum is one game that Nvidia really likes to brag about and it certainly looks impressive with PhysX as it could be the only game that really adds that final touch to the overall feeling and gameplay.
Even without PhysX the GTX 480 is the king of the hill, especially if you add some quality with AA and AF. This didn't came as a surprise considering that GTX 285 is doing a hell of a job in this game with or without PhysX and the GTX 480 was designed to be much faster than the GTX 285.
When PhysX is enabled you can clearly see how much faster is the GTX 480 when compared to the GTX 285. Even at higher resolutions we are quite sure that GTX 480 could possibly give a playable framerate.
