Sheesh, so many hyptothetical. The differences between these CPUs is nothing. The only way you'll know if it matters at all is by testing it all, which makes me side by
@USAFRet. Effort is everything.
In the end spent so much time thinking this out and you'll get 0 accurate answer as there is no one here who has both CPUs and has tested them both in your usecase.
My two cents are that you're probably going to notice a tiny performance bump, if there's any bump at all. Don't bring DDR4 into this mix as well.. If so, replace your entire Mobo/CPU/RAM combo for a i5-6600K or better or any Ryzen series.
