THIS one. I got it and it runs max shaders and max other graphics on BL without a problem. (9000+ bricks)
It can run other games on medium / high as well, such as The Elder Scrolls V: Skyrim (60-65 fps on high, not ultra), Mirror's Edge (70-90 fps on medium/high)
The only con about this card is that AA and fog don't agree with it that much. (Slows it down a ton, but not unplayable, 30-40 fps on medium/high, 8xAA on Mirror's Edge.)
Also comes with a 75$ in game coupon. Not sure what for though...
