I wouldn't make that assumption. I could very easily see the dual Xeon outperforming the dual Opteron -- make sure to test the specific application first. In fact, I would wager that the dual Xeon will outperform the Opteron in most situations, based on my experience. The Opteron 240 seems to be performing somewhere between an XP 2000+ and XP 2200+; not even up to Athlon MP levels yet -- based on my testing, which is by no means exhaustive. And hyperthreading can make a very significant difference for many types of loads, too. Be sure to benchmark what you are actually going to be using the machine for. A lot of us work under the assumption that "64-bit is faster," and that's not necessarily true. Best Regards, -- Daniel Robbins Chief Architect, Gentoo Linux http://www.gentoo.org
