I know a guy willing to sell me his Mac Pro for 1500. Its about two years old, 1st gen Xeon Processor, quad core, 3 xtra hard drives, don't know how much ram, 4 gigs I think. I was just about to buy a new Mac Pro Quad Core with the Nephalem processor for 2300(student discount), when the deal came my way. What should I do? Planning to run Final Cut Pro and Protools on it mostly. Will I wish I had gotten the newer version in a year or two? Will it be a significant difference in performance of the newer computer vs the older version? Can the processor be upgraded at a later date? Tell me what you can, cast your vote, throw me some advise and opinions and help me make a decision. For the record, I am leaning towards the computer with the regular xeon(older) over the nephalem(newer) processor. 800 hundred dollar difference...hard to beat, unless you know something that I need to know. Talk to me folks
