[SOLVED] What display should I use?

[sithlordconn]

Current Setup:
EVGA GTX1080Ti
i7-8700k (limited edition)
Asus ROG Z390 Mobo
16gb Corsair Vengeance RAM
EVGA 750W Platinum PWR SUP

Main Game:
Destiny 2

Current Monitor:
Samsung UJ59 4K @ 60Hz

The questions are:

Is it worth upgrading my monitor to something with a higher response time / refresh rate?
For a game like Destiny 2 is it better to have a TN / IPS / VA monitor?
Can this rig as is run Destiny 2 in 4k @ 144Hz if I upgraded the display?
Would I need a second 1080Ti to run Destiny 2 in 4k @ 144Hz,
or would I need to jump to a 2080Ti?
Is the CPU capable of running Destiny 2 on 4k @ 144Hz?

Install FRAPS, disable VSync and test for yourself.
