some mobo not ready to support dual core GPU
need to update new mobo bios.
then the different with pci-e slot 1.0 and 2.0,depend on the mobo pci slot,but only will show improve with very very high resolution

wow any improve for 4870x2?

yo...try on cryis d
got few fps improve
nice~

very high still cannot i think
with the amd fusion beta,still can add 20-40% performance on gaming like crysis.still wait for the 64bit version haih haih

yeah i playing warhead now
4870x2
enthusiast fps 25-40 mostly
glad to say it is....playable!

i tried on warhead also
not really make different on fps
dunno why

i set the videomem to 2048 then get few fps gain
that's help play smoother with enthusiast
