This is a difficult call.  I picked up the CPU and MB, with a 16M stick for
less than $350 (don't remember exactly), which I considered a deal at the

If you'd like a faster CPU, but would rather split some of the budget out
for a nice PCI 2M video card, or a nicer mouse, or a quadspin CD, these
aren't a bad choice.  (And AMD's 5k86 line screams)

Out in the sticks, (Iowa) the 5x86 has been a nice upgrade for several of my
machines with money invested in nice VLB video.  

In the first case, I was given $1200 to spread across six machines, and get
the max yield.  Result: almost doubled everyone's memory, and the /33s went
to /160s, rather than buy -one- low end P5/75.  

And my experience has been that for heavy math, (Usually FFTs) the 160s run
roughly as fast as the P5-90s.  You could do worse.

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

Must be nice.  :)
