Should I get a 4k monitor?

[CyberpowerPC07]

I just finished my new build and plan on updating my monitor (currently have a BenQ 1080p 60hz). So, I've looked at benchmarks etc for my card at 1440, 4k, ultra wide, etc and it performs fairly well, but I want a second opinion before I invest that much into a monitor. Is 4K worth the price?

Build:
i7 Skylake 6700k
Gigabyte z170x gaming 7
Gigabyte GTX 1070
Hyper 212 Evo x (dual fan setup)
Corsair HX 850 PSU
16gb DDR4 Corsair Vengeance
(If I missed anything let me know)

First of all, 1440 is 2k and not 4k. 2160 is 4k. Second, it depends on what you wanna do with the monitor. If you wanna game, then 4k will be too much for a 1070 to handle, specially with modern games like BF1. Whereas if you wanna use it as HTPC, then you should be fine.
