I stand corrected, and having had the opportunity to play with some Opteron kit since I wrote the reply above, I must agree that they do provide excellent performance in both IA32 and AMD64 modes. Prices aren't even too outrageous, considering the extra performance. Lead time for getting the kit is a little longer than for the Xeons, and our supplier can't do a 1U Opteron rack mount with dual power supplies yet, but those are minor considerations. Guess we're going to be getting a few more AMD64 boxes coming in, in future.
