Zerk2012 :
Not at 2K resolution for gaming no your video card is to weak.
WRONG.
The GTX1050Ti supports up to 2560x1440 at 240Hz via Displayport
It's listed as supporting DP v1.4:

I think you are confusing the ability to update the monitor with FPS in games but those are completely separate.
Most games probably should be set to 1920x1080, and adjust the settings to achieve the ideal balance of visuals and FPS (i.e 50FPS average for Assassin's Creed?).
the MONITOR should be set to scale by ASPECT
Obviously should be using GSYNC.
I would not run that monitor at 180Hz, not even 165Hz. I would stick with 144Hz likely (whatever default is) as the power draw may cause the fan to spin high even in desktop mode, and OVERCLOCKING can cause video issues (i.e. slightly incorrect color to overdrive being problematic).
You can experiment with that.
OTHER: just FYI, but 2K resolution is 1920x1080
