Any true benchmarks specifically comparing 6970 CF versus single 7970?

There is a lot of benchmarks out there for 79xx but nothing really specific for comparing 6970 CF versus single 7970?

It's quite easy:

6970 CF:
455

7970:
700

A quick overclock to 950/1450 on the 6970 gave Legitreviews a 7% increase, so if you use that as a estimate then 6970 CF @ 950/1450 would give ~ 10418p

So to wrap it up:

6970 CF @ Stock = GPU score 9737p
6970 CF @ 950/1450 = GPU 10418p (Estimate)
7970 @ Stock = GPU 7600p (21.9% behind stock 6970s / 27% behind overclocked 6970s)
7970 @ 1125/6300 = GPU 9046p (9.0% behind stock 6970s / 18% behind overclocked 6970s)
7970 @ 1165/6500 = GPU 9389p (3.8% behind stock 6970s / 11.3% behind overclocked 6970s )

That is in 3dMark 11 GPU score only.

What bench are you looking for? I could prolly do an apples to apples comparison between my available rigs.

You should do that. Every generation people say, oh buy the best single gpu then crossfire later. Later something better is out and its always a debate which to do. Happened with my 5850, and now with my 6970 lol.

I tried SLI with 8800GT's for about a week after they were outdated, didnt have any issues. Have always been kind of curious to try CF/SLI in my main rig.

Looks like a 6990 is 20% faster than a 7970, and 6970CF would be a little faster than a 6990. 7970 Beat 6990 in only 1 benchmark for fps, and that was Batman Arkham City. Both cards got sub 60fps. I'm assuming it isn't coded well for CF.
