I want to purchase a new mac. I had an imac g5 17inch. I use my computer for web design and graphic design. I was looking at the new iMacs and know that they are all glossy screen now, I don't want to drop 2500+ on a MacPro and a display so I was looking at used/open box macs on the site powermax i saw an iMac with a 20" display, Intel Core 2 Duo 2.16 but its the previous generation with the matte screen I was wondering if I should go that route or get a G5 Power Mac with 2.0 Ghz. I mostly use Adobe products to design and sometimes use Soundbooth to edit Audio. I was wondering if it is a bad idea to take a step backwards and get the Power Mac, although it is more upgradeable, versus being stuck with only 3 gigs of ram. Advice would be greatly appreciated.
