am running sierra on a optiplex 780 with a pny gt 710. I followed a step by step guide here. My machine boots fine and actually shows that the pny 710 is recognized I have attached a link with proof. My issue is when I am doing anything that relates to video it artifacts and slows alot. I understand that this is a cheap graphics card but from what I read online it seems like the other hackintoshes dont have this issue with this card. I am wondering if you have had any similar problems or solutions to this. I also have attached my config file. I asked around on reddit and they said this could be related to the qe/ci. I am pretty new at this so I don't know how to enable this. I have installed the web drivers for 10.12.6 and that hasnt changed anything.
