If you ever do get the chance to try it out on a 4K monitor + gtx 1080, please do tell me how it goes!
Currently I'm on an 1080p $90 monitor from amazon and a gtx 1050. One day I hope to save up enough to get the latest rig (:
It also runs well on the "Beautiful" quality setting on my 5 year old HP laptop which uses a NVIDIA Quadro K2100M.
