finally got motivated to do some OCing, although i'm still tweaking the final cpu voltage:

hardware: evga 680i A1, qx6700, 8800 gtx sli, raptors raid 0

water cooling: single loop with pa120.3, dtek fuzion, danger den gpu blocks

air cooling: nb has hr-05 and sb has hr-05 sli by thermalright

8 x 437.5 (1750) = 3500mhz
vcore 1.425
fsb 1.5
spp 1.45
mcp/spp auto

temps at 26C ambient: idle 38, load (4cores 100% prime95) 46C, nb 43C, gpu 51 and 54C
