To followup to my own post...  As I posted in another message...

On the other hand, in spite of the speed improvements, my simple
Pentium 120 blows the doors off my 5x86-133.  So, keep things in
perspective.  The 5x86 is a good cheap upgrade for an existing old 486

If you're going to buy new, definitely avoid the 5x86 (486) parts and
head straight for Pentium (or P6).  If you're on a really tight
budget, try to find a closeout-special on a Triton-1 board and a P100.
Even that will be way faster than a 5x86-133.

(My P120 is an Asus P55TP4N [Triton-1] board.)
