Paying for a gaming video card that can do 4k , is an extra dimension of pointlessness . Unless you are playing the game in a CINEMA"
You did read the article you linked to, right? Where they explained patiently that *viewing distance matters*?
I haven't yet updated to a 4k capable PC, so I've got no skin in this game, but I tend to be playing about 50cm from the screen rather than a more normal TV viewing distance of 2+ metres.
My next PC will have a 4k display because extra resolution is incredibly useful for work (my current PC has 3 monitors, a single large 4k screen will replace them all). Will gaming look any better? Probably, but I'll be using VR goggles instead (viewing distance: 5cm) :)
