Here's my experience, I ran 9.1 on the stock 180 MHz processor for about a year and was very satisfied. For a comparison, at the same time I had a PowerMac 6100 with a 210 MHz G3 upgrade card in it. On that machine, 9.1 was very pokey; I went back to 8.6. So, I think have an idea of when 9.1 is too much. This summer I put a G3 card in my 2400c. The difference was noticeable, but not particularly dramatic. I'd have few qualms about going back to the stock 180 with 9.1 if I had to. I think the bus speed on the 2400 must be just enough to give what 9.1 needs. That's my € 0.0161184.
