also look at this
hd7970 is dominating in compute, so while kepler is a bit more efficient in games it happens to be for the price of compute(but i would take that with a grain of salt as this review about compute isnt extensive enough)
but dang this round it looks like both amd and nvidia are kinda switching places! or more or less becoming very similar
EDIT: also i just realized this test is using an i7 920 while the other is using an intel sandy bridge extreme, the difference between the 2 is interesting
and here the driver used is 11.12, any reason why you didnt use catalyst 12.2 w1zz? since i believe thats the one that adds support to hd7970(im assuming because they dont make a great difference and the release hd7970 results are being compared with kepler)
In the exact page you linked the GTX680 beats the HD7970 in 2/3 resolutions. The HD7970 only wins at 1920x1200, and at that res it's only ahead by 1fps, which is well within the MoE. By your logic I could point to the bottom chart (1680x1050) and say "oh look, the GTX570 is faster than the HD7970!" As for Compute, it's 50/50. Half the time it runs about as well as the 580, half the time it runs like a 560Ti. As long as the GTX680 can perform in games, it's a winner in my book (especially being smaller, less power hungry, quieter, and cooler than the HD7970).
As for the test bench, this has come up every review. W1z has done several benchmarks proving the OCed i7-920 is not holding back the setup. While SB is technically faster, when testing GPU's it's largely irrelevant. The difference even in the most CPU-bound game he runs (SC2) was only a few percentage points.
