Interesting. Andree, what are your Mac's general specs?
I have Mac Pro from 2009 with 12 core 3.46GHz CPUs. I currently only have a single GPU in it: AMD RX 480 8GB.
Unless you are debayering raw at high res and high quality, the CPUs aren't really a huge factor in performance in Resolve; any somewhat modern price/performance CPU will do just fine.
With a 2k timeline, my RX480 manages most things nicely. If I go to a UHD timeline (I only have the free demo installed, not the Studio), I get 25 fps playback with Canon raw light files with basic adjustments, and it drops to 21-22 with a larger node tree. It is my plan to sell the RX480 and drop in two RX580 as a price/performance solution until I know more about either the iMac Pro or the next Mac Pro.
