My 2008 MacPro is starting to feel slow. Its been my workhorse for 7 years and I have more than made my moneys worth on this machine. It's running FCP 7 and Adobe CS5 currently. My core apps are FCP 7, thinking about going to X, if not Premiere, After Effects, Photoshop, Illustrator, InDesign on occasion for print material, and probably the entire Creative Cloud from Adobe. We also plan to edit 4k video soon so I need the MacPro to run Davinci Resolve and/or SpeedGrade smoothly as well. My plan is to store all the media on an external Thunderbolt 2.0 Pegasus R6/R8 which should be sufficient for speed. So my question is what is the ideal setup? I was thinking about a 256GB Internal HD for apps and OS only, 3.5GHz 6-core, 32GB RAM, and Dual AMD FirePro D700 GPUs with 6GB of GDDR5 VRAM each. Any reason why I should get the faster processors or more RAM? Where will I see the performance increase? Quicker render and export video times? Thanks in advance for any advice.
