Read the other thread "advice on Mac for PS use"
I'm with everyone else that's posted so far. You gain very little
with a new G4. Fix the one you have.
I also strongly agree with using OS 9 over X.
I have been using my new mirror door dual 1 gig Power Mac for about
a month now. I still have my G4 400. When you suggest there is very
little difference between those two machines, you really need to
have both in house to compare. I can tell you there is much more
performance increase with this new machine than there is with the
G4 400 over my B&W G3 400. This new machine is in a whole new
category. If you already have a good monitor, I'd go for a new
Power mac.. I think you will be tremendously impressed.
As for your G4 400. If you haven't done firmware updates with it,
you will probably find using X and even 9.2.2 is a little buggy. Do
the latest updates. Also try your machine without any of your third
party ram. Ram problems have been a big deal the last year or so
with our Macs.
