Well, it's been about 3 days, but I think everything stable, only thing is, I feel that there's a bit much voltage needed for 2.9Ghz(1.45v), it shows up as 1.48 in CPU-Z. I tried running 1.425v and it shut down in the middle of 3dMark06, 1.45 keeps everything stable with CPU burn-in for 6 hours (2 instances) All in all, I'm really satisfied with this new rig, 5122 in 3DMark06 for a $105 dollar card, not bad..
