waiting on my i7-7700K (at 4.7 GHz all core)/Z270/32 GB of RAM/Samsung 960 EVO/GTX1060 to at least 'not seem quick any more' before planning an upgrade...; so far that has not happened, as it still seems just as fast /responsive as when assembled more than 5.25 years ago.
(I will watch what happens with Intel's 13th gen and AMD's 7000 series comparisons with great interest... but as I've not even launched my one game of Battlefield 1 in probably 3 months, it might take the alleged upcoming price drops on RTX3000 series might trigger, and some very compelling performance lifts to make me upgrade, which would then relegate this system to TrueNAS or OpenMediaVault duties.)
