its about time a new gpu came out with significant gains
we need a new '8800gtx' and i personally doubt that ati can deliver on that
Surprised to read that you would even expect such gpu right now considering it's going to be on 40nm process again. Won't see the gains you are talking about until 28nm is out next year.
Look at nvidia, they could not improve their top gpu by 50% let alone the gains your talking about. With that said I think it's a bit obvious ati will at best beat the 580 gtx by a small margin, which by the way would be a much bigger improvement from the 5870.
Don't see why someone who has a 5850/70 or 470/480 would get all exited about the 580 or 6970. If anything maybe the 6990. The real gains will come next year. Will likely be getting cards that will be double the speed of 580/6970. Then one can get all exited.
As I said before, the 7970/780 will be great cards and be worth upgrading for
