You forgot to mention "perform for a specific application"  ;-)
(and particular RAM, controller, ....)

Unfortunately most benchmarks on the web are highly irrelevant for me.
( Game frame rates , office productivity tools, ....)

I recently stopped miss-using my Dual Xeon 2.8GHz test machine for kernel 
compile duties
and bought and used a cheap Athlon XP 2500/Barton instead.
( While I am normally a SCSI only guy due to the higher MTBF - I tested the 
SATA waters
with the Raptor drive (the first non SCSI drive with decent MTBF) for this box)

While I am certain that a benchmark would show the Xeon machine way ahead on 
compiles
it really makes no practical difference for me.
