I'm curious because of the specs b/n the two cards. It would "appear" that the only thing holding the 7970 back is it's core and memory clock speeds. If it was overclocked to be closer to the GTX680 levels, I think the 7970 would beat the GTX680 due to it bigger bus size.

Here are some graphs for OC'd 7970 http://www.3dnews.ru/video/626473/index2.htm (scroll down for game tests).
I think you can find same in English.

Chinese is easy

S!

Codex..I am currently running my 7970HD at 1000/1450MHz. Totally stable and keeps cool still. I really have not noted the "noisy fan" all the reviews talk about. Checked temps after IL-2 session and they were a tad above 60'C..

Here is the test with both cards OC'ed to max:

Maximum clock will vary from card to card, but i think that in general gtx680 has a bit better OC potential.
Also GK104 was produced as performance chip, not high end.
That is obvious from ~300 mm^2 chip surface and 256 bit memory bus.
From the leaks before release it may be concluded that in first nvidia
planned to name it 670 Ti

Probably when they got first samples, realized that they can clock it higher then expected and beat 7970 at least at 1980 and 2560 resolutions,
so they finaly realised card as gtx680.

The lackluster compute performance and inferior memory bandwidth will hurt the GTX 680 in multi-screen, maxed out image quality, high end gaming.

Very interesting. Now given that I use multi-screen but don't overclock should I go for the 680GTX or 7970? (Would be waiting for the bigger memory version of the 680)
