I am a student who is currently starting to work on some at home projects with cartoon animation (Toon Boom) and Video Editing (Final Cut/After Effects). I have a Dual 2.0 G5 with 1G Ram. Would there be a signifigant advantage in upgrading to a Dual 2.8 Mac Pro? I could probably get 700-800 dollars for the current computer so, would dropping 2000 on a new tower give me a huge boost in performance? (Money is kind of an issue but not if the difference is staggering.) Or should I just upgrade the RAM on my current tower, be happy with what I have and quit jabbering? Thanks.
