He's probably not using a bridge right now with one card. But he was told to use two with two cards. Just offering advice from my experience.

Dont overclock the cards especially the memory. Also i would do a clean Windows Install. What drivers are you using? I get 6K with 2500K @ 4.8Ghz and stock HD 6970. You should be getting ~ 5K+

ok don't shout at me .......... but u have turned CF on in cat control centre, it does reset some times i've had to do it one or twice. It should be in the same bit as amd overdrive

U only need to connect one bridge. U have to so you can connect three cards.

If you still don't get an appropriate frame rate I suggest you close all other windows such as internet or video playing programs. I have had this slow my cards down (even though they are only 5770s) and would explain terrible scores.

Also check to make sure your card is coming out of it's 2D state when running the benchmark. My 6970 will sometimes stay at like 500 mhz or something, I've caught it doing this in Afterburner several times and a restart was the only way I could get it to right itself.

Crossfired 6970's - P5805

For comparison what I got from corssfired 5870's - P6914

And from a single GTX580 - P5850

Something is definitely messed up I need help brainstorming what might be wrong.
