Personally I'm a AMD fan. Intel dumped a ton of money into their Itanium line and aren't getting the results they wanted out of it. So far all the articles I've read on people running the Dual Opteron boards have been very positive. Along with some of the benchmarks that I've seen of the Athlon 64. One thing to keep in mind is that Intel is gonna drop the 2 MB L2 cache Pentium 4 chips on the market before they do anything. And the bonus is that you don't have to but a new motherboard to take advantage of the extra cache. Kinda cool.
