yesir, the 7850 is a single 6 pin device, will use less power, be more quiet and cooler than the 5870 as well as have 3 games. i would go with the ghost from xfx.
No, but to be honest, I'm not really interested with any of those games included. Which one is better for shere performance, I know the 7850 2gb is better by a bit, but I'm not sure how much the 1gb version will suffer
