running a 1070 here with an MG279q, all is working good. I used CRU to bump the free sync range from 35-90 up to 60-144 and enabled g-sync. not had any issues so far other than a small flick to a black screen with PUBG but this is so quick and does not happen very often, unsure if this is PUBG or the drive but I am very pleased with the outcome of this as I play games such as world of Warcraft which has a rep for low FPS in cities and raiding it is nice to have a smooth look with all the chaos that is going on.
Might be worth making an LTT spreadsheet in order to keep track of setups that work and take a note oh what issue people have cropped up with and possible fixes
