I am currently looking at getting a new monitor, but these days there are so many choices - 1080p, 1440p, 4K, Curved and the standard flat variety and probably other specs that I have missed. 
Anyway, I am looking at a couple of models, but would like advice please if they would be fine with my setup, which comprises an AMD Ryzen 5 2600, 16GB RAM and a 4GB Asus RX570 GPU. 
The models are a Dell 27" Curved Gaming Monitor: Curved Gaming Monitor: Dell 27 Monitor - S2721HGF | Dell New Zealand A Dell 27" QHD IPS Dell 27 Monitor: S2721DS | Dell New Zealand 

Currently I am using an Asus VS238 60Hz which has a TN panel. The Dell Curved Gaming Monitor has a refresh rate of 144Hz while the QHD is 75Hz.  Typical use for me when using the computer is web browsing, office, streaming, some photo editing and some gaming - I don't really do First Person Shooters but do occasionally play Rocket League, while other game time consists of games like Frost Punk, Cities Skylines, and other simulation games. 

So in saying all that, out of the two monitors mentioned, which is the better choice? Would my graphics card work fine with the 144Hz Curved Gaming Monitor or would I be better with the higher resolution 27" QHD 75Hz monitor, but again, would my graphics card work fine with it? Fine as in no frames per seconds dropped in say Rocket League?  I did look at a 32" Curved AOC monitor too, but being only 1080p, and I am usually sitting about 550mm away from the screen, I figured that I would probably see too many pixels being that close. Any help is much appreciated.
