CPUs — The more CPUs the better, however if your database does not
use many complex functions your money is best spent on a better
disk subsystem. Also, avoid Intel Xeon processors with PostgreSQL
as there is a problem with the context switching in these
processors that gives sub-par performance. Opterons are generally
accepted as being a superior CPU for PostgreSQL databases.

Is this still true in regards to Xeon's? I was looking at a server
with Quad Core Xeon 2 5335 @ 2.0GHz.
And at http://www.powerpostgresql.com/PerfList
It seems to be outdated. As far as I know it was supposed to warn for
the HyperThreading things.
