My friend who just upgraded his GPU from the 1050ti to the 1080, doesn't seem too satisfied with the upgrade. While the fps has increased considerably (1920*1080) there are frequent drops in his framerate, he also told me that his frametime tends to jump to 27ms while playing BF1 in full lobbies and CPU hits 99% usage. His CPU is a Core i5 7600k (stock clock), I was wondering if he'd notice any change if he upgraded to an i7 7700k.
