Core 2 or Opteron

  Hello,

  We're planning new server or two for PostgreSQL and I'm wondering Intel
Core 2 (Woodcrest for servers?) or Opteron is faster for PostgreSQL now?

  When I look through hardware sites Core 2 wins. But I believe those tests
mostly are being done in 32 bits. Does the picture change in 64 bits?

  And I also remember that in PostgreSQL Opteron earlier had huge advantage
over older Xeons. But did Intel manage to change picture now?

  Thanks,

  Mindaugas
