Would it be better to upgrade my i5 2400 and get a gtx 1070 rather than keep the i5 2400 and get a gtx 1080. I'm looking to play games such as Just Cause 3, Battlefield 4, Rust and H1Z1 (and League of Legends but anything can run that). I want to upgrade to a 144 Hz monitor as well as people say it is a huge improvement over 60 Hz. Which upgrade would give me the most FPS in the games I want to play?
