Even a much weaker ryzen 3 1200 4 thread cpu will not limit a gtx 1050 in most titles excluding gtav, a cpu hungry game. Your 3770 is much more powerfull so i wouldnt worry about it. A gtx 1050 can deliver 60 fps in most games at 1080p low-medium settings. Some older titles can be cranked up to max.
I get 120fps at full hd settings cranked to max with aa and everthing in tf2. I can even crank my resolution to 4k and still have 60fps maxed out.
Cs go is great 1080p maxed.
Fortnite stutters at any settings at 1080p but will run at 60fps medium settings with unplayable freezes and stutters. Id expect the same from pubg although i cant confirm this.
In GTAV at 1080p high settings with no motion blur and no aa i get 80fps limited by my cpu. My gpu is only at 75%.
With a more powerfull 3770k you will run into purely gpu limits and have decent performance.
