No rainmaster the 5 series graphics cards cant run Bioshock. You need a 6600GT. Thats the lowest of the low that will play it. Find a nice cheap 256mb 7900 or a 512mb 6800.
I have both pc and 360 and compared them. I ran the 360 in HDMI at 1080P and my PC is a Core2Duo/2Gig/640mb 8800. I ran the PC in 1920x1080 since thats the same rez as Xbox. Not a HUGE difference but the PC did look a bit better. I didnt like the mouse and keys so I used a controller since this is more of a console game in my opinion.
