    Maybe that's because the GPU is be clocked too high, I thought the core clock is derived from PCIe bus frequency on the new Geforce 9 cards. I may be mistaken, but maybe you could make a little test:
    1. run all test with standard clocks and PCIe at 110,
    2. run test with core clock increased by 10% and PCIe at 100

    Just my thoughts.

    Nice results by the way, I think I need a new gfx too...

    yep , i think all 9000 series have that !

    if the relation PCI frequency/GPU clock is the same as 9600GT , then 9800GX2 Default using PCI-E @ 110Mhz = 660Mhz Default Clock (600x1.10)


    nice scores pedro !

    regards
