I currently have a 2008 Mac Pro 8 core 2.8Ghz with of 18GB ram, the HD 5870 and an SSD. It's showing its age and I'm looking for a replacement. I'm considering the 2009 8 core 2.93Ghz or a new 2012 6 core 3.33Ghz. I'm looking for better performance with FCPX, Motion and Compressor. My current Mac Pro works fine for my other uses. Would either of these be a big improvement performance wise? I do use the Mac Pro for my video production business. I've also considered getting the Retina Macbook Pro, but I can't find anything online about how it really performs with FCPX. Any advice would be greatly appreciated.
