Hi,

Yes you will want to run them with 64-bit linux. The biggest reason to do so in your case is to allow mysqld to address more than 2G or 4G of ram. If you run with a 32-bit system, then mysqld will be restricted to one of the other values. mysqld internally uses a lot of 64-bit numbers, so that might give some performance difference as well, but the RAM is the largest key in this case.

A lot of large MySQL users are running on Opterons under 64-bit linux such as LiveJournal and Wikipedia.
