For those who want to undrstand WHY Moreno may be reticent to do such a
comparison, start at:

http://www.arstechnica.com/ask-ars/2000/ask-11202000.html

Keep in mind that all the PIII chips since about 99 have been made with
Coppermine technology, the PIII technology referenced in the article...
  I've got dual PIII1000e (Coppermine) CPUs... If you buy PIIIs make sure
they are Coppermine..

Also try this link for fuller comparisons including Macs:

http://macspeedzone.com/archive/html/hardw/misc/a/win_vs_mac/ray.html

To get any significant increased Performance of a  Xeon PIII over a
Coppermine PIII (and that mostly in database type apps) you need more
than 256k on die L2 cache...

Chip prices for those chips are double or more than of a PIII Coppermine...

There is no way in hell you will get more than a 10% performance
increase in PShop over a similar Coppermine equipped PIII...

FOR ACTUAL Photoshop tests check:

http://www.digit-life.com/articles/pentium4xeonsmp/

As you will read there, even SMP won't give more than a max of 15% on
average in  PShop.. (Filtering operations may IMHO be about 60% faster
on a dual CPU than a single CPU -- so a dualie only makes sense if like 
I,  you are doing a lot of filtering, and the additional L2 cache of the 
Xeon ain't gonna boost that much..)

Since Pshop still uses a lot of  disk caching (scratch disk), me
suspects the RAID array makes a big difference in Moreno's numbers...
