If I may jump in, though, what about the buss speed? Doesn't that put a damper on any processor improvement?
thanks
I wouldn't say it's a damper, but....
The bus speed does cause a bottleneck. The faster the CPU is the more of a bottleneck the bus speed will be.
I had a 300MHz G3 in my PTP 250 which made a noticeable difference in speed and responsiveness.
I will be installing a 375MHz G3 card soon, but I wouldn't bother with anything faster due to the speed of the bus and the RAM.
At some point I think it is overkill and a waste of the CPU's ability. The performance/dollar boost ratio drops as you go higher in CPU speeds.
If I was to put a 1GHz G4 card in the PTP it would never run like a 1GHz G4 should.
I found the CPU's used and relatively cheap. If I had to buy a new G3 card for the PowerTower Pro I would probably skip it and just go with a newer Mac like a B&W G3 which has the 100MHz bus and PC100 RAM.
