The major drawback for PC gaming at 4k that I never see mentioned is how much heat the panels generate. Many of them generate so much heat that rely on active cooling! I bought a pair of high refresh 4k displays and combined with the PC, they raised my room to an uncomfortable temperature. I returned them for other reasons (hard to justify not returning them when I got laid off a week after purchasing them), but I've since made note of the wattage when scouting monitors.
That was earlier this year. I found a new job with a pay raise so it turned out alright. Still miss my old team though.. we've been scattered like straws in the wind.
