So my specs are: Mac Pro (Mid 2010) - running Mac OS High Sierra 10.13.6 2.8 GHz Quad-Core Intel Xeon 32 GB 1066 MHz DDR3 ram ATI Radeon HD 5770 1024 MB Apple 30" Cinema Display (2560 x 1600) I didn't account for any issues and have been chugging along just fine (after a max RAM upgrade a year ago). I didn't notice until after I updated to High Sierra that my GPU readings (in Activity Monitor) are non existent. I get no readings. I discovered this after opening an older Premiere Pro project that now gives all kinds of "Low Level Exception" errors. I'd like to know if this is the end of the road for me and the Mac Pro (2010)? If I can get the Video Card upgraded, I'd be more than thrilled to keep chugging along with this ol faithful tower. My son just purchased a new Video Card and has a hand me down card, that's not all that lacking that might work... or so I'd like to think. He has an EVGA GeForce GTX 1060 FTW2, 6GB GDDR5 (link): https://www.evga.com/products/product.aspx?pn=06G-P4-6766-KR From what I can tell, it's clearly not "Mac" ready, but is there an option for compatibility with the Mac (via drivers, etc.)? Also, I am overall concerned with how the GPU readings are blank... and can only assume it's because the factory stock card is outdated as far as supported by the current OS. Still, it bothers me to have no readings and seemingly non-existent in performance when tasked with graphic intense apps. Could there be other quirks that I need to address aside from simply upgrading the GPU? Thanks!
