it depends what type of games or genre of games you are into before i can start making some recommendations...
...personally i play lots of various games eg:
Fifa and Pro Evo
[recently played the godfather, was fun for a while with ok gfx]
You can always try and find a ps3 emulator with motostorm and test your gfx, but i dont know if you can and i wouldnt know how
as i try to stay away from the illegal side.
