I've been looking, but I can't find any benches with the 680 using KGB against an overclocked 7970... can you link?
If you speaking on benching items, there's none, 7970 Ghz wins hands down. We of the benching team can tell you that much. Go to hwbot.org and see for yourself, this is what I meant by "7970Ghz wins in benching"
In games though, it is different, as the driver probably has a lot to do with it, and I find NVDA drivers more optimal. I cannot find an example with KGB mod, but here's a stock comparison of GTX680 with 7970Ghz. in this example the GTX680 beats 7970Ghz -on stock-.. so when OC-ed, and KGB applied.. you do the math. and I have seen in many forums people claiming GTX670 on KGB approaches 7970Ghz performance too. (I haven't tested it.. but I do not think it is impossible either.. driver optimization for games.. can make very large difference.)
This is what I mean by "In games, I find NVDA GPUs better", this might be related to GPU-CPU sync or just flat our driver optimization, I do not know. but it is quite clear that GTX680 can easily go head to head on 7970Ghz on most of the recent games.
Like I said, both cards have their perks, saying either is better than the other is not a very correct way of describing the results at all.
EDIT: I found a good comparison page for everyone: http://www.techpowerup.com/reviews/ASUS/ARES_II/27.html
This is done in January, includes all we want to compare in the above talks.
on OC: 7970Ghz can probably get up to 1360Mhz without crashing, GTX 680 can get to 1306Mhz (on KGB) both of which is around the same 10% boost from stock OC.
So if we use this comparison, and extrapolate the results, I will say GTX680 and 7970Ghz is really all about the same.
