The GPU's are at 64C and 60C everything in the PC is under 65C. I don't think heat is an issue.

Is that load temps, if so how are you loading the GPU's while reading the temps? With a game or with something like FurMark?

Bizarre.

Sorry you're having trouble. I've run GTX 260 SLi and mixed GTX 260 Tri-SLi without problems on the Evga X58 mobo and with a healthy overclock. I was using 180.48, and now I'm using 181.22.

If I think of something for you to try. I'll let you know.

I had a lot crashing with games on 790 Ultra and I never did figure that one out. I think 790 Ultra was under volting my Q6600 which made it unstable.

Make sure your BIOS didn't reset your ram voltage or CPU voltage too low. A lot of performance ram needs on the order of 1.60v to be stable. The Evga mobo will default to 1.5v for the ram, I believe.

I'm getting no scaling with my SLI 285s in ETQW.

I've tried running games in both Vista and XP, but they still crash after a few minutes. I decided to take the ASUS board back and exchange it for a GIGABYTE EX58-UD4P, but the exact same thing still happens. I know the video cards are good because they worked perfectly for 2 years with my old board, so I definately say it's a chipset issue. I hope there's a fix for this soon.

So after more troubleshooting, I discovered the freezing issue was actually caused by one of my video cards, and not the mainboard. After RMAing the bad card, it no longer crashes in SLI. However, now I'm seeing horizontal flickering lines in all games that run in SLI , which I'm pretty sure has something to do with vsync. The new card is slightly overclocked from the factory, but automatically downclocks to match the speed of the reference card.
