I've seen this board in the labs with Crossfire as well. It allows overclocking either from bios or from IDCC (Intel's own software). There's a burn-in option in the software to allow OC on the fly. Be wary though, warranty due to burnt CPUs/boards might not be entertained.

Nope, there's Intel D955XBK, D955XCS and a few others that already has overclocking capabilities. Shoo shoo, dun be lazy, go and google for info. Google is POWER.
