are you going more towards performance, or do you want graphics? both are tricky to achieve in a lot of games. ill look at my pcsx2 emulator and see what my settings are. i havent used it in about a month, but after i get off from work ill post them if you would still like a starting point. i play alot of action oriented games (Castlevania, DragonBall Z, etc.). ideally, your settings should get you in the neighborhood of 60 fps (any higher and the game will actually speed). honestly, many of my games are unplayable past 70 fps ( there are settings that lock the highest fps i think) these are things to think about tho.
