[VR-Zone] Powercolor ATi HD3870 X2 tweaking

Switching over to Windows XP and Performance mipmaps, we ended up with 918MHz/1134MHz on the GPU/MEM clocks. This was acheived with 1.49V on BN:4 and 1.43V on BN:3 (all voltages measured in 3D mode). Memory voltage was untouched. GPU quality differs across the board, so expect to treat them like individuals graphics accelerators when voltage tweaking.

With 2.27V on memory, 1.59V on Vref, 1.55V on BN:4 and 1.49V on BN:3, 22.7K score in 3DMark06 was taken. The only let down was the poor matching of the GPU cores (one could perform at 1012MHz with a slight voltage bump).
