Check out the Kawaii Codec Pack. It was technically made for anime, but it is basically a fully-set-up version of MPC-HC + MadVR + other stuff so that you don't have to spend the couple of hours trying to set things up manually. With your rig, just max out the presets in the KCP utility. And then go into MadVR (play a video in MPC-HC then go to the little icon bar thingy on the bottom right side of Windows and find MadVR, and go into settings) and set up the SuperRes in there and sharpening. You end up with one heck of a good looking video compared to VLC or vanilla MPC-HC. I use VLC on my Mac too, but really only because MPV just completely sucks overall in its current form. The only thing MPV for OS X has for it is picture quality, but everything else about it is so unpolished it hurts.
