The folks over at NordicHardware have news of a very impressive overclock that netted them a final score of 33622 in 3DMark.
The graphics cards were running at 920/980MHz, while the processor, an Intel Core 2 Extreme X6800, was pushed to 5280MHz (440x12) using a mousepot rev3. The motherboard was (a personal favorite of mine), Abit AW9D-MAX, paired with Teamgroup OPB Edition running at 1:1 3-3-3-4 and a Tagan 1100W power supply.
