Uh, BD, why do you think this?

Intel certainly believes that the Celeron includes MMX (see:

I upgraded from a P266 MMX: bought an Abit motherboard and a Celeron 333 
for about $180 *total*.  Over-clocked the Celeron to 504 mHz using Abit's 
software, and installed a couple of extra fans in the cabinet to keep the 
CPU temp down.  Total cost not much more than $200.  The cost of a PIII 
500mHz chip *alone* is nearly three times that.  The Celeron uses a 
different caching system than the Pentium, but I'm not sure how interesting 
the differences would be to Luggers.

This set-up runs circles around the P266, and the added speed is 
dramatically noticeable during scanning, image processing, and printing, 
which place the main processing load on my system.

I also added a two-year-old Matrox Millennium 10MB video card, which was a 
state-of-the-art 2D card when it was released.  Cost new well over $400.  I 
bought it on eBay for $50.  I used the 3D card that I already have for the 
second monitor.  Windows98/Adobe allow me to adjust the gamma separately 
for both monitors.

A no-holds-barred system, in my view, would look like this:

Dual 500+mHz processors
256 MB system RAM (minimum)
8+ gig HD, wide SCSI or UltraDMA IDE, 7200 RPM.
2 monitors/cards to suit one taste and budget, at least one of the combos 
*really* good for image editing.
CD R/W (I have a first generation 2x write that works OK, but is slooooow.)
Nikon LS-2000 or equivalent scanner.
Other drives, devices to suit one particular needs.
Printer of one's choice.

I use an Epson Perfection 636 (USB) flatbed with a transparency adapter to 
scan 6x9 stuff.  Here's where a fast/large hard disk is absolutely 
essential.  An ordinary transparency scanned at full resolution at actual 
size generates a .tiff file of about +/- 30MB.  A 6x9 scanned at the same 
resolution/size can generate an image file approaching a gig in size.  Add 
PS's workspace requirements, and we're talking multiple gigs to process a 
single image.  Suffice it to say, I can't work at this level on my present 
system (I scan 6x9cm at 35mm dimensions--with a subsequent loss in image 
quality), but I can imagine putting together a system that could . . .
