I currently have a Mac Pro 3.1 (2008) 8-Core, 12GB ram and a Radeon HD 4870 (512 MB ram). OS and apps run from an SSD drive, all date is stored on regular hard drives. My main uses are regular desktop admin stuff (email, browsing, etc.), some light music recording, and some Adobe CS4 applications (Photoshop, Premiere Pro, Illustrator). None of this on a professional level, just hobbies. It still does all of those things, but some of them could be faster and smoother (looking at video editing, mainly). And after 7 1/2 years with this machine, I'm slowly starting to get that itch. If I got a good deal on a lowest-spec Mac Pro 2013 and put 32 gigs of ram into it, would it make a huge difference in performance? Or would I need to spend money on the higher end options (6 Core, D500...) to really make it worth the jump?
