I have a Powerbook G4 1.33 1gig of ram. I am currently looking to buy a iMac 17inch g5. Will I notice a big diff in stuff I do for example dvd buring. Video editing. Small gaming nothing too fancey. Or should I just hold off for a while and get a dual 3.0 when they come out in the powermacs. Anyone that has a new imac please let me know how u like it and comparisons.
