buying a new Linux number cruncher - Pentium 3 or Xeon processors?

For a number cruncher, why do you prefer a dual processor box instead of two
single-processor ones ? Size ? Or are you planning to run two-processor jobs
We have very successfully used small clusters of top-line Linux-driven
Athlons for our crystallographic processing, they were both cheaper and
faster than their contemporary Intel equivalents. Last purchase was about a
year ago - I am not 100% sure that the same will hold today.
