-------------I have a G3 upgrade card and some 7300s, 7500s and 7600s. All of various speeds from 100 to 200 mHz. Which is the best platform? And does the basic speed make a difference? Jerry
I had a similar situation. The 7500/7600 have audio/video inputs, if you
consider them useful. According to Guru, they also have a 50mhz system
bus as opposed to the 7300's 48mhz system bus.
Other that that, since you will be pulling the processor card for the upgrade, there isn't much difference that I can see.
What I did was "cannibalize" the suite of machines to stack up the most
RAM, trying to gain both the max and match pairs of DIMMs for optimum
interleave, fill all VRAM slots, put together the best "plastics" and
fastest CD-ROM with the largest hard drive. Now have a "frankenMac" that
is a pretty fair machine.

The Bus speed of the 7300-9600, & the clones based off them, is controlled by the CPU card. Most G3 & all G4 cards support a 50 MHz Bus setting & unless you change it in software thats what you'll be using. The 7300/180 I'm typing on has a 400 MHz Sonnet G3 & is running on a 50 MHz bus. One thing to note is that on XLR8yourmac.com they tested some XLR8 accelerators & they found that 49.6 MHZ was the optimum speed for those cards. Go figure.
