I currently have a 4790K on an ASRock Z97 Extreme4 and an EVGA GTX980-SC, is it worthwhile upgrading the CPU or the GPU more? I play games like R6S, Division, GhostRecon, PU BG, BF1, etc. I was thinking a GTX1080 since GTX1080ti just came out, but would upgrading to a newer processor help more or less than a GPU upgrade?
