Well, I haven't had a chance to run PostgreSQL on a quad-Opteron box,
but in discussing this with someone building a cluster out of them,
their experience is that they are seeing better performance out of a
quad-Opteron than a 3Ghz Xeon box (quad as well), which they believe
reflects superior memory architecture.  So, if someone has run on a
quad-Xeon of similar "specs", then I would imagine you should see
similar, if not better, numbers.
