The main advantage of the new Xeons is that they support multithreading (making a single CPU appear as multiple CPUs. In a multithreaded app this can increase the speed of the application by 10-30% over a non multithreaded CPU (the next P4 will also support this - but for now it is only available in the Xeons). In a non multithreaded application there is apparently a small performance penalty (I have not seen a benchmark quantifying this however) The main disadvantage of a Xeon CPU, is that you would need 2 (so they would cost twice as much), are only available at 2.4 (vs 2.53Mhz), and are not yet offered with the 533 FSB (only 400). As for the incremental bump from the 2.4A to the 2.4B or 2.5Mhz CPUs - the 533 FSB results in a 5 or so % increase in performance at a given frequency from the extra memory bandwidth. Currently the best price performance CPU is the 2.26 CPU which has a 533FSB, and is available in the mid 200$ range.
