Is INNO3d good makers of GPU?
you gpu is fine inno is a good make, although I would have suggested a 460. Both your ram and cpu are going to be limiters (probably in that order) You'll get good on all the games except gtaiv. I imagine it'll still be playable.. but with 2 gigs of memory, it's bound to stutter or hang
edit: Have fun playing prototype, sick game that didn't get enough coverage
