It supports it of course. You may run into a bottleneck in some games due to cpu performance, ddr3 memory wont cause any bottleneck, in most games the difference between ddr3 and ddr4 ram at any speed is small or non existent. The severity of the bottleneck depends on the game and the framerates you want to achieve. I can max most games 1080p 60fps with a fx 6350 and gtx 1060 6gb but I dont get much over 60fps in modern AAA titles. GTA V and fallout 4 come to mind as games that i see a cpu bottleneck with, that said I am still able to get close to max settings 60fps smooth gameplay.
