Getting a more powerful CPU might
help you some, you do say after all that this is your profession, so if
that is the case getting a more powerful tower based system seems like
a sensible move and a worthy investment.
It was me who said I might get the G5 - but not only for the greater amount of power - with the hope that the newer hardware is somehow more compatible with the software. I have a G4/400 with a sonnet 1.2ghz upgrade board, extra RAM, a Radeon 9000 graphics board, etc. I have all sorts of things crash at times - more than just logic - so I was taking your (Dennis's) system as an inspiration.
Someone mentioned that the bus speeds are half of the processor speeds (e.g for 1.8 ghz cpu the buss is 900 mhz, etc). However, Apple put out a single CPU 1.8 where the bus speed was 600 mhz, which is 3:1 compared to 2:1). So its not always 2:1 and perhaps the difference is what allows the second CPU to access the same ram.
My reason for multiplying the numbers is this ... if water flowed through a pipe a certain speed, but then you put something which cut the effciency to 90% at some bottle neck, then a second change which cuts it down 90% then the cumulative effect (of the two "resistors" in series) is .9*.9 = .81 = 81% efficiency.
