Did I say the fastest?  Nope...  I said "similar"...

i.e. a 1.4mhZ PIIIeb vs a 1.4 mHz PIIIXeon w/512k L2

PhotoShop AFAIK never does EVERYTHING in RAM..  It's memory model is 
flawed.. There is one way around that.. But you need really beaucoup 
RAM, and utilities that M$ doesn't approve of.... You  create a LARGE 
VRAM disk and use that as your scratch disk..

You know, with all the cheap RAM, if you have 4-8 gB running on a 
machine or two, I'd love to see if something like that helped....  Any 
chance you'd be willing to give it a shot and let us know if it was any 
faster?  I know under earlier versions of  PShop that trick could help.. 
(of course we weren't using 1 or 2 GB RAM disks..
