One thing I can say beyond a doubt.  I have been running on this quad 2.0ghz
opteron, and I have now seen 10M NPS in several positions.  I have _never_
seen any single CPU machine that will produce 2.5M nps.  For example, my 2.8
will do about 1/2 of that using one cpu, while the opteron is producing 2.5M
on a single processor, and acutally a bit more as the NPS is not scaling
perfectly.

It is an impressive procssor, at least for what I am doing.
