I am looking to buy a new mac after Macworld, but I need some help. I know this is done often around here, but what better place to ask than those who know best? I will mainly be using a computer for home/office use. I will do some light graphic design, light editing on Final Cut, and DVD Authoring on DVD Studio Pro. Do you think the iMac will suffice, or will I need a PowerMac? I obviously like the iMac price and space efficiency better, but what will get me far? Thanks ahead for taking the time to help me out.
