This is my current gaming PC and it works wonderfully however I was wondering which part I should upgrade first and why I. I know there are new 1080 and other GPUs and Ryzen processors so maybe I could upgrade to one of them?

are you satisfied with your pc? I would wait for the next gen graphics cards..
