I know this question has been asked a dozen times and Ive read all the threads, but I wanted to give specifics for my situation and get some opinions. I am trying to decide between the iMac 27 2.93 Quad Core i7 and the Mac Pro. I will be using the machine for multi-camera HD video editing in Final Cut Pro. The footage is from two Canon Vixias, a Canon 60D and a Canon XHA-1. (4 camera angles total) Clips can be as long as 30 minutes each. (no 3D editing) Question 1. Will the quad core iMac equipped with an eSATA port from OWC (for external hd) handle what I am trying to do? Question 2. If I need to go up to the Mac Pro, how far up do I need to go to see a big difference in process/render times? (do I need the hex-core to see a difference?) Question 3. For either machine what is the minimum RAM you suggest. Ive read that FCP doesnt use over 8gb. Is that true? Question 4. When it comes to graphics cards, a couple of the refurbished Mac Pros have 512mb cards. Is that a problem? Misc. info: I dont mind having my desk cluttered with external drives if I get the iMac. If I get the Mac Pro I will have to sacrifice on display and get a 20 or 23 off eBay. (Ive already got a 17 so, Ill have dual displays) Im less worried about upgrading in the future and more worried about speed right now. My budget is about $2800 (trying to stay under 3k) Hope this wasnt too long I appreciate the help!
