3 7970's beating 4 580s is pretty impressive even though I'll never be anywhere near either setup.

I am however on newegg right now flipping back and forth between the 7950 and 7970 trying to decide what to get...

Getting a 200mhz overclock with the 7970 is practically the norm, while most 580 users will struggle with that unless they get a golden card like a classified or msi lightning.
Secondly, the 1260 oc in my chart is not a 40% overclock. The 7970 scales better than the GTX 580, as per those figures.

Not sure why you think my figures are wrong. They're pulled from the hardocp website and rounded to nearest whole percentage. Your right though I based my numbers off the highest vs highest achievable clocks. I would point out that there are some differences between your chart and what they got at the 1300 clock. Like Dues ex; they show only a 19% increase over reference and your chart that shows 31% difference. OH well, yes it does overclock higher, no question about that.

Reference 7970 (note: NOT the gigabyte model)
1325889231KTNbsOX8Vr_7_2.gif
Asus GTX 580 ROG 1005 MHZ: 22% faster on average when oc'ed
Radeon HD 7970: 30% faster on average when oc'ed, and 50-80% faster than an oc'ed GTX 580.
I find that looking at cold hard objective data is very helpful when making these determinations, instead of making lame "i love brand X" arguments with no substance. 7970 achieves higher mhz overclocks than does the GTX 580 and scales around 30% when oc'ed -- and also performs near 80% faster than the GTX 580 when oc'ed to 1300mhz.

I'm confused on where you see that the gtx 580 is @ 1ghz?

Was from a previous Review that they did. Think he had a link if not there was one in my previous post.

Hmm, why does AMD consistently get low minimum fps from back in the 5000 series? Is it the drivers or something?

Nope, it is mostly irrelevant or something.

Its just the games. Looks the the graphs. Both GTX580 and HD 7970 dip in the same place. It could the the CPU.
