I'd just like to hop in and recommend the same card that Denther's got (the 7850 2gb). I do have a 500 W PSU, and it works just fine. I also have a 1080P monitor. I get 35+ frame rates on Tomb Raider, Bioshock Infinite, and Far Cry 3 Blood Dragon, all on max settings. So if you've got the cash, I highly recommend it!
