so i bought a 1080p 240hz monitor (which by the way is smooth asf) and i have an i7 6700k, however ive been running into a lot of issues with this processor so ive decided to get rid of that and the asus z170 sabertooth for a new mobo and new cpu. i have ordered a 1070 which comes tomorrow. My question is, what cpu should i get (and mobo) to get about 100fps+ in games like witcher 3, assassins creed origins, middle earth shadow of war. my budget ranges from 300-600 (mobo+cpu) but i dont want to pay an extra £100 for 5fps or something, any suggestions? thank you
