My system: Dual Core E2200 @ 2.2 Ghz 3 Gig RAM Geforce 9600 GT 1 Gb All settings on high (Ambient Occlusion off) 30 to 50 fps (depends on the game scenes)

I play the game with my Geforce 9400 GT that it's slower than the 8600 GTS and I have a Dual Core E2200 I play at 1024 x 768 and all settings on high except the shadows are off I get 35 to 40 fps the game's engine is amazing!! my low end card still has some chance in these days :P:P

Moral in games is way off the real life in Bioshock harvesting the little sisters is a most I say, to be able to use all the adam there is in Fallout 3, stealing an empty cup makes you loose Karma, and I think the best moral choice you take in fallout 3, is either destroying Megaton or not, so stealing things or killing innocents in games does not makes you Immoral
