Yepp, we need a 64-bit Geekbench score for a 3.2 quad. I still have the feeling that the 3.2 GHz quad and the 2.66 dodeca will be the "sweet spots".
It's not a perfect comparison.. but I took my i7-980X and dropped it down to 3.2GHz and 4 cores in BIOS.
In Win7 I get 9670 on 64 bit Geekbench with 6GB RAM.
