I have a 2010 Mac Pro 5,1 2.8 GHz Quad Core with 16GB on which I’m running Harmony 12. It has the stock Radeon 5770 video card and I’m starting to see issues even though I’m not even using any fancy effects yet. For instance, I have a drawing that has dozens of thin stripes done with the line tool and when I’ve gone back to do touch ups, there are glitches that sometimes put in extra color where I don’t want it - then other times it works just fine. I think it’s because of my underpowered graphics card. As I’m not super tech oriented, I’d like to upgrade to either an official Mac edition card or one that has been flashed so that I get a boot screen.
I’ve narrowed it down to three cards, all of which will improve my performance:
- Nvidia GTX 970 4GB - there are no official Mac editions of this card, only ones that have been flashed and I have to download drivers from Nvidia but it will be the highest performing.
- GTX 760 - apparently these do not have to be flashed to work on Macs.
- AMD Sapphire 7950 - there are official Mac editions of this card, as well as PC editions that have been flashed. I would only be interested in an official Mac edition. I think it will be the lowest performing of the three choices.
I’d love Mac Pro owners using Harmony to weigh in on this!
