although I will point out that just clock speed is not everything. I did a
bunch of tests last week with different cpu speeds and found that
different generations of chips were very different, to the point where a
2.3GHz core (in a 2x4-core opteron system) gave me approximatly double the
performance of a 2.6GHz core (in a 2x2-core opteron system) or a 3GHz core
(in a 1x1-core opteron system)
