I don't know what you boys are talking about, right now with folding GPU2 clients are the king.
I have 5 quad core Q66009 and none of them are dedicated folders. My daily output are coming out of 3 dual pci-e slotted mobo , all three have dual video cards. That is only six (6) 8800gs/9600gso combo. Each pumping out 4750ppd each. The ppd might change when Stanford change the point system but more core does not equate to more production for now.
