"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

More info like the model numbers's of the cpu's would be most helpful.
That's right - there is no comparison between the Netburst Xeons and the newer Conroe Xeons: http://en.wikipedia.org/wiki/Xeon.  The Opterons are better than the former and worse than the latter.

Single Processor, Quad Core Intel Xeon L5420
Ok, that's the specs for quad core Intel. Whats the model # of the Opterons?
The L5420 is a low-powered version of the E5420, running at 2.50GHz, so that places it approximately halfway between the 3.0GHz E5450 (score of 4181) and the 2.0GHz E5405 (score of 3257): http://www.cpubenchmark.net/high_end_cpus.html.  The best dual cpu configuration is the Opteron 2222 (score of 2882), so that means no dual Opteron setup can come close - you need a quad cpu Opteron 8218 (score of 5082) to beat it.

If you're running with 16GB RAM for the Xeon, that tilts the advantage even more in its favor over the 4GB RAM for the Opterons.
