I run in 4K with graphics options at maximum on an i7-4790K at 4.2Ghz, 16Gb RAM and Geforce GTX970 4GB. It runs OK with the very occasional stuttering however the framerate is noticeably lower than 1080p and leads to some jerkyness when panning the camera. It not enough to bother me though.
Edit: What does help is installing the game to a SSD. Hardly any stuttering when panning the camera.
