I currently rock an i5 4670k and a gtx 980ti in my current rig. Like many other people, I am going to purchase the new gtx 1080 and sell my current video card. I am wondering though, is it worth the money to also upgrade my CPU to the i7 4790k? ; will upgrading to a better CPU actually give me a considerable gaming boost?. I currently game on 1440p, and should I upgrade to the i7 4790k or not?, or maybe a different CPU all together?
