Congrats on the new build and good luck with the overclock.
I did clock vs clock comparisons back in 2014-2016 for Sandy\Ivy Bridge using some of the highest rated overclocks on both of those platforms. This is before Ryzen and Intel latest and greatest dropped. At the time I was thinking about going Sandy\Ivy Bridge-E. Saved a lot of money in the process based on my findings. Maybe others will think otherwise, but it wasn't that "big" of a jump for me. Especially when you look at all the money that "could" have been involved.
