I plan to mildly overclock... This is my first build for myself. Do you guys think this rig will be able to play The Witcher 3 on Medium-High settings with decent fps? 
This is the first time I've gone with an AMD card, the other pc's that I built have been with NVIDIA cards... I hope the card performs well otherwise it will be a first bad impression... lol
