I personally have a gtx 1070 and a ryzen 5 1600 as well as a 1080p 144hz monitor. For the most part it is ok out I feel like I should have spent more on the cpu to take full advantage of my 1070. In games like gta 5 and ping you can definitely notice the bottleneck compared to the new ryzen cpu's or Intel's coffe lake line of processors. It really depends on the game you are playing.
Hope this could help
