Wow, yeah 3.45 is pretty damn fast and 1 grand a big sum to pay if you ush it to hard and kill something. Are your video cards overclocked any?
Unfortunatly for me when I got this system I didnt know the definision of OC so I got a board without a PCI/AGP lock so my max stable OC is 2.35
ASUS K8V Se Dx (saved my ass a few times but OCs like dog shit)
AMD64 3200+ S754 ClawHammer
BFG 6800 Ultra
512 mbs OCZ Platinum El PC-3200 2-2-2-5 on UPS truck commin here now...
Not comparible to yours but I wish I had a better motherboard, and it might get to 2.5-2.6, when I didnt know about PCI/AGP lock I had it up to 2.4 at 1.86 Vcore before I stoped, did not want to blow anything.
