I've had mine for a few days and I've yet to find a game that it struggles with. Fallout 4, project cars and the witcher 3 are all handled fine with AA off (I can't even notice any improvement with it on). None of these games have dipped below 30fps at any point... Perfectly playable. Why did some people (not on here) say that it couldn't handle 4k properly... What planet are they on!!
