I've seen these aplenty in video editing sweatshops. It's not so much the editing that presses the CPU(s), but any effects or encoding.
Simple editing and you can skimp on the CPU.
Can I ask why your Apple contact can't discuss this? Most are far more knowledgable than your usual PC dispenser.
I've been looking at Mac hardware for the last few weeks and am preparing to make the switch from PC. Basically, the only reason I'm interested in a Mac is Final Cut Pro. I've narrowed my choice down to the I Mac 20" and the PowerMac 2GHz. What I want to know is how much of a difference the dual processor makes? The Power Mac is about $350 more with less features ao I'm assuming that's the big reason for the price difference.
Also, if anyone has any experience with Final Cut, is the dual display capability of the Power Mac worth the extra money or is the single screen sufficient? Thanks in advance for any help
