Sorry not an option in your system the rest of the systems logic would need to be swapped out as well (which is not practical) your system is based on Kaby Lake the new 8th gen is using Coffee Lake architecture while similar it’s not drop in compatible.

This is possible,It has been done on motherboards from third party vendors, apples logic is no different, What is needed is a patch for the bootloader, or a spoof in the efi and the compatibility fix added to it that was done with z170 motherboards.Whoever does it first will get a ton of rep.For now though if you can get a 7700k, you wont be disappointing, And I wouldn’t hold your breath on anyone in the mac community putting as much trial & error and time into this.(Just saw that its quite a few months old, didnt mean to revive the dead thread).I also swapped in a 7700k from an i5, tricky but rewarding.

Yes its easy on a Windows PC, Mac's are a very different beast! Its just not that easy. Unless you've got the skills to dig deep into the firmware its just not possible!
