Many thanks ShoNuff!

Unfortunately, tragedy struck after 2.5 days. I had some weird problems with my VC's before I tore the system apart for this build, but I figured it was probably driver bugs. I got a CMOS ERR on my LCD poster today...so I reset the CMOS and everything was fine, or so I thought. I booted again and everything was fine. A few minutes later "POP" and one of my VC's was gone.
I got a bit nervous, did I wire something wrong? I wouldn't think so after at least 48 hours of run time. Taking no chances, I pulled my 1Kw SS Strider out of my server and used it cables on the new rig. Same results. I then popped the Zeus into the server and the server worked fine. It still is four hours later.
Needless to say I have strung out everywhere! However, I did manage to get the i7 to 4.0 with no problems and my temps were excellent. My water temp was consistently between 30-32C and the highest core temp I saw was 64C. I was too busy tweaking to post any screen shots.
Since I will be tearing everything down again, big sigh, I have to decide if I should upgrade the VC's or stick with the 280's. If I do decide to upgrade should I go nuts and get 2x295's or 2x285's?
BTW, I will probably sleeve the Strider as it will totally solve my PCI-e wiring problems! Thoughts?
