Considering your plan is to upgrade now and keep your system 3-5yrs even if you go with the the most powerfull GPU for the time being , aka 4090 , you will be GPU limited at 4K , 14900K or else .

As showcased by CPU scaling there is no difference at 4K between a 13900K/7800X3D/13700K when driven by a 4090 . Hell you can even go down to i5 teritorry and see as little as 2-3% perf drop which you can't perceive. In the future you will be even more GPU limited within those 3-5yrs with more demanding games coming out etc .
Bottom line is CPU isn't your priority, GPU is and considering you are not going to wait for next gen GPUs , anything over a 7800X3D/13700K you are just throwing money out of the window for no reason other than throwing money out of the window . Don't get me wrong if that's your thing then all good but if you are doing so under the impression that you are ''futureproofing'' your system then it's an erroneous impression.
Wasted money will do you much better service when invested into future upgrades or something entirely else !
