Imo, I don't think it'll be worth gaming or even buying a 4K for quite a long time unless you do photo/video editing or other production work!
If you had plenty of money i bet you would be tempted to try Ultra high definition?. Or try downsampling?. I like the sound of "Pixels Per Degree of Vision (PPD)" . Expensive hobby is gaming and benching

..."the biggest overall benefit of 4K is the massive increase in Pixels Per Degree of Vision (PPD). Folks in white coats believe an eye in good working order can distinguish 50 Pixels Per Degree of Vision, taking into account the amount of pixels per inch of screen, and the distance of the viewer from it. With gaming monitors we tend to sit far closer than we do with TVs, and so the screen begins to envelop our cone of vision.
Using the average eye quality and view distances determined by scientists, a 27 inch 1920x1080 monitor, the most popular size and resolution, has a PPD of 19.3, meaning there are 19.3 pixels to guide the eye per degree of vision when sat 20 inches away. When observed closely, the screen can appear grainy, and the individual pixels are easily distinguished. 30 inch 2560x1600 monitors, first introduced in 2006, improve matters somewhat, upping the PPD to 24.7, and the visible quality of the screen by 28%.
New 4K, 31.5 inch 3840x2160 monitors crank the PPD all the way up to an unprecedented 35.6, increasing the visible quality of the screen by 84% when compared to the 1920x1080, 27 inch screen. This tight grouping of pixels per degree of vision helps textures appear more realistic, makes text, numbers and HUDs amazingly sharp and defined, and makes individual pixels nigh on indistinguishable. Scientifically, your eyes begin to
believe that the game rendered on-screen is as real as the Real World, drawing you in and immersing you like never before."
With a PPD of 35.6, the quality of 31.5 inch, 3840x2160 4K monitors is 84% higher than the quality of 27 inch, 1920x1080 HD monitors, significantly increasing the image quality of every single screen element.
Of course, to
play games at 4K you’re going to need a top-end system, one that features SLI GeForce GTX 770s, GTX 780s, or GTX SLI TITANs. Only these configurations have the performance to power games like
Assassin's Creed IV: Black Flag,
Batman: Arkham Origins,
Call of Duty: Ghosts, and
Watch_Dogs to their maximum potential.
