Just an i7-8750H in a laptop .. so aging a little now, but never had a single issue with it...
And yeah, the unbalanced database thing is a thing, but i never get that far into saves for it to be noticeable..... and it's mostly when you end up with just one or two leagues really..
My current game save i use has 26 leagues from mostly europe and the same 220k or so players...
