If I could find an extra 128MB of RAM to double it's memory, I'd be quite willing to try it.
Well, apparently, you could buy a CPU upgrade, and slap in an 800 mhz G4 processor (which should perform approximately equal to, oh, a 1.4 ghz P4?).
I could throw a 1.6 GHz Athlon XP into one of those old abominable ECS motherboards with the SDR and DDR memory slots and run it off SDR-SDRAM, but I doubt it'd perform as well as my 1.6 running on DDR. While I imagine there's quite a performance increase, I doubt that G4 is really operating at it's full potential.
Well, of course it's not at it's FULL potential...the bus speed of the motherboard limits it.
It'll probably perform almost as well as a normal 800 mhz G4, with the exception of games and Photoshop (and other things that make a lot of use of the system bus). But you'd be stupid to try to run modern 3d games on a PowerMac 8500 anyway

Um, I'm pretty sure the max upgrade is a 500MHz G4...which should be roughly equvilant to a 500MHz K7.

Intel released a Pentium II/333 upgrade for the Pentium Pro. Give it enough RAM and it'll run XP, though you probably should turn off Luna.
Also, some guy on Ars got a hold of an ALR 6-way PPro machine and promptly put W2K Advanced Server on it

Well, W2k server probably isn't too intensive. They get to cut down the GUI effects on servers. What I mean is with a full GUI, all effects enabled, etc.
In general, Macs aren't bogged down by special effects, because they have a system called Quartz Extreme, that uses the graphics card to 3d render the entire desktop and make some awesome effects, taking the load off the processor for drawing the desktop completely. It's slated to be copied by Microsuck in Longhorn, with Avalon.
However, a PowerMac 8500 wouldn't have such a graphics card, which means the effects WOULD slow it down a bit. So being able to run OS X on such a machine is even MORE impressive.
However, we're talking about from a 180 mhz to a 800 mhz processor. Over 4 times increase, plus the velocity engine in the G4 to give even more performance. I'd imagine it'd be about equivilant to replacing a Pentium Pro with a 1 ghz Pentium 3...
As for the upgrade being 500 mhz, check here:
You will dress you links in the future
Note the upgrade, G4 800 mhz, 1 MB cache
