I found a seller getting rid of his nMP Quad Core that was Apple upgraded to 16gb RAM w/Applecare for $2836 shipped and no tax. Wondering if I should jump on this. He says it's only a few weeks old and Applecare will cover it through 2017. I use FCPX to edit and currently use a 2.3ghz i7 Mac Mini for my work, but it's feeling like a bit laggy since the FCPX 10.1.2 update during background rendering and I'm doing larger and larger projects. I was considering a higher end iMac but didn't want to go the BTO route so I can avoid the insanely high sales tax in Cali and still find a way to get some financing. Any advice? Is this Macpro worth buying at this price? I've been looking into getting one but am hesitant to pull the trigger. Thanks!
