But i'm about to be a first time iMac owner (yay!) and i was wondering if the upgrade from 2.8ghz to 3.06ghz is really worth the money? I plan on going to 4gb of ram.. and i know Mac's usually run much faster on less RAM than a PC, and my current PC is 3.25gb of ran and runs perfectly. The biggest app i really plan on running is probably Photoshop. Any opinions on this is appreciated greatly.. same for opinions on anything else i should know about getting my first Apple computer.. thanks!
