I need some very quick advise, I need to know if I'm going to see a huge difference in speed between a 2.0 and 2.3 dual-core G5? I am only going to be using it fore Aperture 2 and Final Cut Studio 2. I figure if it was ok for professionals back then it should be sufficient for an amateur like myself today. I already know about flash videos like youtube and such not working very well and of course 1080p content, but I will primarily be using it for aperture, very basic video editing, maybe could just download the last "true" imovie, quicken 2007 for budgeting and serving my ATV2 with content via iTunes. Other than that I can't think of anything else I would use it for that I don't already use my Macbook (early 2008 2.4) for. $200 for 2.0 DC or 350 for 2.3DC Which should I go with?
