If you like ASUS, then it is a pretty good choice. There is a similar model from BenQ for a little less:

GTX1070 can handle about 70FPS in most recent titles at QHD, there are a few that it will probably dip below 60FPS on.
If you like the Acer, ASUS has an identical model in the form of the PG279Q (Which I have), but it is usually a bit more expensive. Both are prone to backlight bleed and IPS glow. Some people are not used to IPS glow effects and it can seem like a defect, but that is typical with IPS and VA panels like these. Backlight bleed is more serious and can cause bright spots and color uniformity issues.
If you don't think you need fast paced response times then you probably don't want to invest in a fast refresh rate monitor (Or if you do, go for 1080p so you can get the most of fast paced games)
I bought mine planning for future upgrades, so at some point I will get a GPU that can handle 144FPS in all titles I play, right now it is closer to half.
