Almost identical hardware specs as yours, though in a small pile in a box right now, and my lovely gtx 1080 reference card is running in my current machine. A very competent setup that is. Love it.
I'm going to re-compile my 6700K with a new mainboard, PSU and case and transfer my NVIDIA-branded 1080 over when I determine what graphics card to get. Maybe an RTX 2190 if such a thing will exist.
Starting to see multiple comments about ray-tracing being more of a marketing gimmick than anything. So, it'll be interesting what Ampere has to offer, the 3060 and 3070 specifically. Ain't spending 1100 + USD for a gpu, that's for sure.
