I do quite a lot of video editing and DVD encoding and my G4 466 is a bit slow for the job. Problem is I dont really want to fork out £1500+ for a lovely new G5 powermac at the moment, ideal though it would be. One option is to get a processor upgrade. There a few out there, single and dual processor, but what would be the best option. So much choice!!!! Also saw a nice new mac mini the other day... so quiet! but would I see a big speed bump if i bought one of them? What experiences do people have with these up grades.
