If you value your time and want to save money before you go the hardware route try a cloud gaming platform like Geforce Now. Get the top tier account, you will always have the best graphics, you can run on any of your existing hardware, and you can fire up additional rigs for your children/friends. If the games you like are available, you never have to wait for updates. If you enjoy modding games this is not for you. All that money you were going to throw at the cpu etc can, if you want, be put towards a really nice monitor and controllers both of which typically outlast the cpu anyway.
