Anyone using a reference design 7990 with their H81 PRO BTC? Care to share you experiences? I've had all kinds of Display Driver stopped working issues when trying to use the 1x slots with powered risers (or unpowered). I could not push the card hard without having this problem. I did manage to have the system stable for short periods - sometimes as long as a day or so, but then the display driver would almost always crash.
I've got a hefty enough Corsair AX1200i and a decent circuit supplying 120V.
I'm now running the card in the 16x slot and it appears to be holding steady at peak performance at 610 Watts (that seems pretty high to me - anyone else's suck that much juice?)

Please share your experiences!
