*cough* in theory *cough*BEn_2600+ is right, it is multiplier unlocked so you can go up as well as down the scale which is helpful for overclocking
aren't some of the BE's cooler. like Q6600 G0 instead of B3
Phenom is "at best" identical clock for clock against Conroe/Kentsfield. That means that in certain benchmarks a 2.4GHz Phenom can match the Q6600.
However in most it's beaten, and in some beaten quite soundly.
As a result it really can't compete with Wolfdale/Yorkfield at all.
It does have a really good price for what it is though. The B2 CPUs were a bit naff but at least the B3s are remotely competitive.
