As I have been trolling this subject for months I just discovered and have been using Throttle-n-Purge & BG Renderer scripts and I can see a huge difference in performance and on my multicore usage in 32-Bit full preview, not realtime but 24/29.9fps. It was the performance I have been waiting for with the new mac pro.
3.5 6core
FirePro D700
128 Ram
1TB Internal SSD
4TB SSD Das drive
1TB SSD Cache drive
All Thunderbolt 2
