Hi. I want to be able to play GTA 5 4k Ultra 60 FPS. What should I upgrade in my current rig? If it's possible to keep the 6300, what video card is best for 4k? Thanks guys.

You're going to need to upgrade your CPU + Mobo and your GPU man.

The display model was 4k at 60fps but that had an Intel 5860 or something in the hexa core series, and sli gtx 980, so its a very heavy game at 4k. The best graphics card out right now is the Titan x but you might want them in sli as well. Thats very expensive though, whats your budget?
