I didnt even reformat with the HD5870 and its much smoother than the GTX 480. Is it faster? I don't know yet, I'm just looking at perception of game play first since using the GTX 480 thats been the most disappointing thing about it. The GTX 480 might benchmark faster but as of now BF BC2 runs much, much better on the HD5870. I wish the GTX 480 was this smooth since it gets great numbers in game.
I've got some numbers to compare and will do that soon. right now I'm just going through the games the GTX 480 wasn't running smoothly to compare.
Assassin's Creed II is smoother and benchmarked just as fast. Crysis is just as fast.
Your claims are starting to get irritating at this point (and suspect), these 'problems' are definitely on your end and nothing to do with the 480 (unless it is defective).
Enjoy your 5870, sell the 480 and be done with it.
