Diamond XOC bios 795/1100: P8762 GPU 8783 CPU 8701 1st 2 tests FPS 24.87/26.62 Idle 78c Load 85c

Asustek Top bios 815/925 : P8775 GPU 8838 CPU 8593 1st 2 tests FPS 25.09/26.72 Idle 54c Load 65c

Asus Top autotune: 865/1090

Diamond XOC autotune: 835/1150

Impression: At least on my Visiontek card (stock cooler) the Diamond XOC bios would pass Vantage BUT did not entirely seem stable as would rarely artifact but annoyingly would stutter and jump frames.
On the otherhand, the Asustek Top bios was very smooth and stable. Additionally idle and load temps were much better. Seems to be the better bios with stock cooling.

Additionally from Catalyst 8.7 to 8.8 on the Asus Top bios Vantage scores went from P8357 (24/25) to P8775 (25/26) =)
