I just ordered a abit motherboard from a dealer i sweden. Which bios is the best out right now?

My rig will be:
ABIT AW9D-MAX
C2D E6600
TEAM GROUP PC6400 2X1024
NVIDIA 7800GTX ( X1950XTX COMING SOON )
SEASONIC S12 600W

I like the voltage to vdimm, around 2,6vdimm i can run my memorys at 1200mhz with 5-4-4-15......

Anyone who reach fsb 500+ yet with the abit?
