For your gaming PC you likely don't even need a current gen chip. You are probably fine with a 5600 for most games unless you NEED high FPS on certain games and have a monitor with 244hz refresh rate (or you won't even get the frames) Gaming is mostly about GPU (if you're casual gamer and want to run 1440p) but if you do need cpu and high refresh rate then you're likely hardcore FPS or RTS games and you're running at 1080P anyway and then in that situation don't need a high end GPU.

I have a AMD 7700X and I run it on Eco Mode which is approx 65W TDP instead of the 105W TDP it wants to run at.

For my general use (including cpu intensive operations) this makes absolutely no perceivable difference. I ran some benchmarks out of curiosity and I take about a 5% haircut for a massive power and heat savings.

What Intel and AMD did with the chips was essentially sell consumers a default overclocked chip that will run to the max of the thermal headroom that your fan will allow and sit there. They did this to be competitive with each other in benchmarks for marketing.

Most consumers should run these chips in some sort of eco mode since the performance per watt has severe diminishing returns and they are actually quite power efficient as long as you don't run it on the default factory overclocked settings.
