I need to do some work with some very large graphics files in Photoshop, each just under 700 MB in size. I need the color adjustments to be very good, so I'm looking at getting a Mac. Question: Can a Power Mac G4 1.25 GHz handle 700 MB graphics files, assuming I add quite a bit of RAM, say 1 GB? Is the 1.25 GHz fast enough? I would get a G5/1.6, but the budget is stretched and a dual-G4 would cost nearly as much as a 1.6. Will a single-G4 handle such a file, or realistically should I wait until I can afford a 1.6? What do you think? Thank you so much!
