I only upgraded from my 2009 i7 (I forget the model) to last years i7 because the old motherboard died. I kept upgrading GPU and seeing only 20-30% CPU use while gaming. It was fine. Some changes to how we build these things would be nice. The heavily integrated motherboard model should die. A PCI slot on my old board made the whole system flake. Discrete components I can stack are more my dream design. If my old CPU had been a sealed unit of some kind with a physical connector to the GPU, power, and such, and I could have simply swapped out the faulty port expansion “module”, that would be slick. But one PCI port flaking means I have to bail on an otherwise perfectly functional CPU, RAM, PSU, and cooling kit.
