PPC benchmark numbers are available from Macuser, including processor
score, Pshop and disk tests. Anything that involves moving and
processing data will be improved by both a faster processor, a faster
system bus, larger caches and faster drives. I think your first two
operations involve such, and should be improved.
New PPC machines are waaaaaay past 132 Mz, with Apple just releasing 350
Mz machines, and new PPC 750 Arthur chips on the horizon with even more
processor power and bus speeds of 83 Mz or so. VirtualPC on one of
these boxes should provide you with the ability to run Dos/Win
3.11/Win95/WinNT/OS/2 at very useable speeds if you have the need also.
Don't even bother with a low end 604e unless its a firesale and you're
planning to use it as a layout machine primarily (you can always upgrade
the processor later, heck even a fast 603e with a good size cache is a
better bet IMHO.
I think you'll find it worth the money if you need the power, and of
course the old machine will continue to be productive and make you money
for years and years to come. Heck, we've got old 1987 macs still doing
stuff around the shop, either with accellerators or simply as file
transfer and email machines.
