My i5-4690 and i7-4770 machines remain competitive to this day, even with spectre patches in place. I saw no reason to 'upgrade' to 6/7/8th gen CPUs.
I'm looking for a new desktop now, but for the costs involved I might just end up parting together a HP Z6 G4 with server surplus cpu/ram. The costs of going to 11th+ desktop Intel don't seem worth it.
I'm going to look at the more recent AMD offerings, but I'm not sure they'll compete with surplus server kit.
Whaaat..?
