My experience so far with my system has been great. Constant 60fps at 4k ultra. No complaints, would upgrade my cpu as soon as that wasn't happening and the cpu was the limiting factor. So far any drops was always the gpu and upgrading from my 1080ti to a 2080ti has been great. Then again, I don't play assasins creed or watchdogs (no interest). Anyways back on topic, op should be fine depending on what he is doing. If he's shooting for 4k 60fps, I would personally recommend trying to get as high of an oc as possible to be on the safe side but overall shouldn't be a big deal.
