Do you happen to know how the 64-bit AMD and Xeon would compare when running java code?
One of the groups at work tested an app (serverside java) and they ended up with the following results:
Xeon 32bit - 100% Opteron 32bit - 86% Xeon 64bit - 97% Opteron 64bit - 92%
It was a pretty unbalanced test since we ran a 3.6Ghz Xeon against a much lower speed Opteron (244 I think but I can't verify that until I get to work today) hence the Opteron was quite a bit slower. Anyway, the interesting part was that with the 32 -> 64 bit JDK change boosted performance about 6% on the Opteron while the Xeon actually lost 3%...
