hands on Opterons, but they are worth checking.
However, in combination with the advice appended below, select a nice
EMT Xeon.
Free advice:
1. Ask for Try and Buy from your selected vendor.
2. As for compilers - if it is for computation - avoid gcc like the
yellow varusian heebie-jeebies. Use ICC (the Intel compiler). It will
give you anything from 20% performance gain (unoptimised, just compile
with the thing) to 300% (must use vtune first).
