I'd amend that to say whatever flavor of unix you're most comfortable
with. Many tools aren't quite there on the windows version, and it
still seems to have more issues with performance and scaling than the
unix flavors of PostgreSQL.

I think AMD still has an advantage for CPU >=4 due to the hypertransport
(not cores, actual CPU sockets >=4) Since most loads are easily handled
by two dual core CPUs nowadays, AMD and Intel are about even.
Much more important is your disk subsystem. Using an Areca RAID
controller with battery backed cache and a half dozen or more hard
drives is often the real winner for performance.
