very cache-friendly apps tend to scale more with clock, and thus
run nicely on xeons.

I'd also strongly suggest getting systems with net IPMI; being able to
reset/poweron/poweroff nodes remotely is really very nice. ones I've got
(HP DL145's) also let you collect temperature info much more nicely
than with lm-sensors.
