The forthcoming Nehalem CPU uses on-board memory controllers and NUMA 
designs similar to Opteron.  It should be available Feb/March time frame 
for purchase.  Assuming Arb and RAxML require higher non-blocking memory 
access, current Opteron or future Nehalem will likely be good choices.

This said, some of the units we have built based upon Harpertown (Xeon 
54xx) have been quite fast with BLAST and other codes.  Not as good with

Nehalems will be out soon, if you can wait, you may be able to get this. 
      If you bug your favorite vendor, they may have a unit they can 
provide some access to.
