Not directly Postgres related, but anandtech had a review of DB2 &
MySQL on dual Xeon & Opteron systems. More focused on the differences
between 32bit & 64 bit OS, & Opteron vs Xeon, but possibly of interest:

I have not benchmarked it, but my impression of moving from SuSE 9.2 32bit
to SuSE 9.3 64bit, on the same box, both with a custom compiled similar
Postgres install, is that the 9.3 64bit is faster & more responsive
running Postgres. How much the OS version upgrade vs 32-64 change I can't
say.
Cheers,
