I suspect it could be drivers still too, but I was kinda hoping it wouldn't as drivers I can't do much about apart from wait for AMD to get off their lazy arse and sort things out. I never had any of these issues before AMD bought ATi
I've also tried various CF configs, running stock, the cards are fine in CF, apply any kind of OC and eventually.. VPU recover. Something else I'm trying to figure out is my low 3DMark scores too. In 06 its only 16.8k, and thats with both cards @ 680/2GHz and my Q8400 @ 8*450. Granted, I'm running W7, but I doubt it would have a 2-3k impact on my score. I even seperated and isolated various components attached to my PSU to make sure one rail wasn't overloaded compared to another. Does anybody know if XFX release frequent BIOS updates for their graphics cards like asus do? Maybe its some kind of bug there, wouldn't be the first time. One of my Sapphire HD3870s had a BIOS bug that was never fixed so I had to use a different manufacturers BIOS to fix it.

@ Oki, Don't worry about OT. Its my thread, if I choose to take it OT briefly then so be it
