"...AMD 5x86 PR75. AKA a souped up 486 133..."
Nova, that was a great overclocker (at the time).
I oc'd mine to 160.  Couple that w/16 megs of EDO RAM and I was able to play Quake @ 25 fps @ 512x384.
That was similar performance to a P-75 w/out the P-75 price back in 1994.  I only remember that (Intel's) prices back then were ungodly high.  The same for RAM, too.
