Just to expand upon this, HT does nothing for CPU performance, I hardly say that it does nothing. For everyone else (who may not know,) the hyper-transport link is for all PCI-E and southbridge communication. Pushing HT too high makes your NB on the motherboard work harder (not just the CPU,) and won't result in increased performance. If for some reason you were ever able to saturate HT between video cards, SATA, and such, then you would see a performance boost but that's incredibly unlikely. As for the CPUNB speed, I've found that with the 940, 960t, and 965 that 2.6Ghz was usually a sweet spot without needing too much voltage and offered the best memory performance at 3.4-3.8Ghz on the Phenom IIs I've owned in the past. Maybe I was lucky.
