Tom's Hardware did some benchmarking of MySQL 3.23.52 with the Opteron:

As did Ace's Hardware (3.23.49):

In both cases, the 1.8 ghz Opteron beat out 2.8 ghz Xeons.

I'd like to see some tests with the 64-bit version of MySQL, but I'd feel
pretty confident moving to it for testing.

That's a day I'm really looking forward to. Coming from an Oracle
background, the idea of a single tablespace is, well, disconcerting (though
it's probably only psychological).
