It's a very good pair. You'll be playing Battlefield 1 on Ultra settings very well at 1080p. CPU usage will be 70% to the mid 90's depending on what's happening in the game. The Core i3 4170 can handle it. To set aside any doubts I'll show how my Core i7 4770k does with 2 cores with hyperthreading enabled running at an even lower core clock than the Core i3 4170. Just wait for the video. It's going to be using a GTX 1080.
