I know that I care about single-core performance. All of my desktops are 16-cores. However, my Uncle has a 8-core desktop. In some tests, his desktop did almost as good as mine on a gaming benchmark. The only difference, was that my GPU was an Nvidia RTX 4090 in one of my rigs, and a 4080 in the other. His 8-cores did a great job as far as gaming went. He also had an AMD Radeon RX 7900 XT.
