As many people have said, I would tend to recommend going with
an Athlon. Your bang/$ is much higher -- a 1.53GHz AthlonXP
(i.e. the 1800+) with 1GB of DDR SDRAM is going to be much
cheaper than a 2GHz P4 with 1GB of RDRAM. Do *not*, under any
circumstances, but a P4/SDRAM system.
That being said, the only way to know for sure which system is best
for you is to run *your* code on sample systems and see which runs
better. RDRAM *does* have huge bandwidth, and that can help out
for some types of computations. OTOH, it's latency is higher and that,
combined with the P4's deep pipeline, can mean big penalties for
problems with more random memory access.

For our code, we found Matlab/Linux to be faster than Matlab/NT. We
haven't re-benchmarked with 2K. And, of course, Linux is just
plain better. ;)

AthlonXP 1800+, as much RAM as the mb will hold, and spend the money
saved over a P4 solution on a nice big monitor. :)
