I have been reading these posts here on all the info I can about the imacG5. I plan to use photoshop and Illustrator, but not at a professional level. I came across a thread about this guy running PS on his imacG5 and his Powerbook. He claims that the G5 is slightly slower than the Powerbook. How is this possible? I thought that the Powerbook was G4 based, which according to everyone else, is much slower than the G5. I also read that the single G5 is as fast or faster than a dualG4. Maybe I read too much, or there are some "magic" G4 Powerbooks out there. I would like some straight information on this matter. I think that maybe there are a lot of people out there that think "I have XYZ, therefore XYZ is the best." My Question: Is a G5 imac with 768MB ram and 250GB HD with a G5 1.8 enough for Photoshop to run good? Please remember that I am not using this professionally, and do not want to go the $7000.00 ultra high end dream machine route.
