I've seen quite a few folks touting the Opteron as 2.5x faster with postgres than a Xeon box. What makes the Opteron so quick? Is it that Postgres really prefers to run in 64-bit mode?

The I/O path on the opterons seems to be much faster, and having 64-bit all the way to the disk controller helps... just be sure to run a 64-bit version of your OS.
