Da Vinci recommends 8GB of Vram on the gpu for 4k workflows so provided your gpu meets that spec it should carry the bulk of the workload.

I did used to run the same setup with a gtx 980 and found it workable with some dropframes although now can run smoother playback at the full fps. I work in 4k most of the time running multiple nodes and several stacked timeline layers and have a i7 6700k with 32gb ddr4 ram and a 2080ti which works absolutely fine. Its also very gpu based compared to premiere so although having a decent cpu is good you'd be better off having a chunky gpu and a half way decent cpu (Agree about the 32gb Ram though). Resolve is a node editor so the more nodes you have the more hardware requirement you'll have. Depends what your going to be doing really.
