Yes, that would be very cool and of course the difference would be gigantic, but the hardware hunger over 1080P is just too big for me, despite a GTX 980TI.

In general, I would recommend a 4k or 5k monitor at this sitting distance.
I use this monitor as a secondary monitor in landscape mode and for computer games.
The main monitor is an IPS 27" 5k monitor.
The quality differences are gigantic
