Don't know if this is legal(linking to another forum an all),but here is the PCB anyway
RV770 clocks above 1GHz, launch in May - VR-Zone IT & Lifestyle Forum!
The PCB looks very similar to the HD 3870,so i guess the RV770 might just be souped up RV670 or it might be that they both just use the same PCB
And here is the original link:

I wonder if one of those will out perform an 8800 or a HD 3870 X2
