Ok then here we go. All stock setting on the 975 (133x25=3,33Ghz), DDR3-1600 C8-8-8-28 Tri-Channel Ram. Vcore 1,04/1,08V loaded (HT off/on).

GPU: HD4870X2 @ 820/930
OS: WIn Server 08 x64

Left: HT off, Right: HT on (if you have a big screen.. otherwise it's HT off top, HT on bottom)

Analysis of results: Enable HT for render jobs, disable for gaming.
However, 3D06 results are misleading. Once the CPU gets up to speed (>4Ghz), the score with HT enabled will be a lot better than the one w/o HT.

Lastly, here's what I got on a CB10 max run
