Tom's did a really great graph on $/Performance last week. It really depends on your budget, how long you are looking for the system to last and your use. if you are using a 1080ti I would guess that your gaming at very high resolutions.
Today the i7 7700k is the best gaming CPU and the 8700k is just going to extend that. I would guess that is going to be the case for at least the next 18 months.
On the down side it is the most expensive of the 'normal' CPU's and more and more AAA titles are using enough cores that the 6 and 8 core AMD chips are already very close - especially at the resolutions I expect you to be running at.
You have an i5, so you didn't go for the very top last time, and you have had your current chip for 10 years and I guess you are looking for the longest life possible from your system.
Do you have a definite budget in mind?
Do you want the best right now, or do you want the best bet for the longest lasting CPU?
You are going to love whatever you go for, I suspect that you are in R5 1600X territory on a top AMD board with the opportunity to go to Zen 2 in the future... but with no budget it is hard to recommend...
