Hi,

Simple answer NO !

Your would at the best only have an increase in performance 5% or less. And many commercial codes does not take advantage of the Xeon processor features.

I second that opinion - About a year ago we benchmarked a 500 MHz Xeon against a 500 MHz PIII and the speed difference running both Fluent and our in-house CFD code was negligable.

If you want to buy a small server as a number-cruncher, what would you take ? dual-board with xeons or dual-board with "normal" p3 with same MHz ?
