I will change my GPU from GTX 1050 to a 1070 as well as the RAM to 16gb. Now I don't know if i should upgrade cpu too because in a game like Overwatch i get times whit 100% cpu usage over all 4 cores. Average usage when playing is probably 80-90%, note I'm playing on low settings. So this has made me think what happens when i have a GTX 1070 ofc i'm going to rise the graphics to medium or high but i want to remain at 144fps.
