JC - Thanks for sharing all this good preview info!

Regarding the BOINC benchmark, it is per core, so for total work done the hyperthreading looks promising

If you assume linear scaling with clock speed (big assumption): 3600/2933 = 1.227x

Nehalem @ 3.6 would be:
Whetstone 3418
Drystone 8715

I think there might a difference in OS as well - 64-bit OS has advantage over 32-bit (I think Movieman's numbers were on 64-bit) - some guys are claiming 5-10% difference but maybe someone can confirm/refute this?
