RoninEdits Neither of those GPU's are listed as compatible by Adobe for the Mac version of the software I'm guessing that Adobe just does a poor job of updating this list and the GPU's will work fine? I was considering a GTX 770 as this was the card that was recommended by MacVid Cards for a 3,1 system.but when I checked the Adobe list, the card appeared in the PC side, but NOT the mac side. I think my problem is a combination-performance is not fantastic at any point (which I guess is not fixable with this machine), but it really takes an unacceptable nose-dive once we start adding lumetri effects.
