Ok...last night I finished Mass Effect 2 (Epic Game!!) So it is time to move on to something bigger/better. I am looking for something single player that I can get some hours out of. Also, I am trying to convince the Warden (Wife) to give me the go ahead to grab a 5850 or 5870, so I need something that will bring my 4850 Crossfire rig to its knees. Suggestions please. I have an hour before work is done, so I can grab the game on the way home. Thanks in Advance! P.S. How is the single player BC2? <---Really thinking about this one...or maybe Bioshock 2.
