hello. i am buying a present for someone who is a graphic designer. she currently has a 1.8ghz single G5 PowerMac w/ 2gb ram. i am planning to purchase the aluminum MB 2.0ghz w/ 2gb ram. she has been complaining that the G5 has been running slow, but i'm guessing its due to the clutter on her computer. all the computer is used for is CS4 (illustrator, PS, dreamweaver, flash) and web browsing. what i'm trying to find out is if its worth it to dish out $1300 to upgrade to a 2.0ghz MB from a 1.8ghz G5. i have been told that the Adobe software is SIGNIFICANTLY faster on a C2D compared to a G5. and i'm sure the 2.4ghz MB is worth the extra $300, but not sure if i could afford that. anyone have experience with this?
