The 7970 is not a great card. Sure, the 28nm process allows for decent clock speeds, but ignoring that it is a small step forward from the 6900 series. It has approximately 30% more shaders than the 6970 and a 50% larger memory bus. Clock for clock the 7970 is only ~40% faster than the 6970, which is on-par considering the above shader and memory bus increase. There is very little to be impressed about, other than the shrink itself.
Following suit, NVidia really don't have to redesign the GTX580 too much to beat AMD. Indeed, I would argue they would need to be completely incompetent not to produce a faster card. Even if they make no optimisations whatsoever and simply clone a higher shader Fermi part onto the 28nm process, they should comfortably win. AMD fans may cry out about power consumption and performance per watt, but now that the 7900 includes proper direct compute, it is unlikeley to have any such advantage over NVidia. My guess is that the performance per watt crown can swing either way.
So, stop deluding yourselves. The 7970 is average to disappointing. Kepler is promissing, but entirely unproven. It may be great, good, average or disapppointing, but it will surely be faster than AMD's top card in one form or another. For the timebeing the 7970 is the fastest single GPU card in the world. For the timebeing.
