The only reason you'd get an SGI box is if you need to visualize insane amounts 
of data. SGI still excells at being able to drive their visualization 
environment with a LOT of data without skipping a beat. That being said, your 
raw computational power requirement would be much better fullfilled by a 
Beowulf or Myrinet-style cluster.
