kpf, the difference here is that K7 had an "FSB"(yes I know it's not really an FSB) that couldn't really make use of the increased bandwidth of a dual channel system, whereas K8 has a "PSB" operating at full processor speed which is more than capable of making use of it, just as P4 can better make use of dual channel than K7.
Then, add in the unregistered factor, and 939 may be a nice improvement over FX Socket940. This could be used to deal with any substantial improvement Prescott brings.
