Question i7 12700K/KF vs i7 12700/F (RE gaming build)

Why_Me

Glorious
I see the i7 12700K/KF + Z690 boards recommended a lot on here and elsewhere for gaming builds and other than the Z690 chipset having more PCIe lanes (bandwidth) what is the advantage that setup has vs the i7 12700/F + B660 board in regards to gaming builds?
