Best CPU Upgrade Options for My Current Setup

Your B660m motherboard supports 12th, 13th, and even some 14th gen Intel CPUs. If it's a good quality board, upgrading to something like the i5-13600 might be a cost-effective way to go, but if it’s lacking in VRM quality, I'd stick with AMD for a more future-proof setup.

You might want to look at the i7 12700KF or the 13700KF as solid choices. They're powerful options that should work well with your motherboard, giving you a nice performance boost without needing a complete system overhaul.

If you're gaming at higher resolutions like 1440p, you might not even need to upgrade your CPU right away. The GPU will handle most of the workload at those resolutions, so consider getting the 9070XT first and see how it performs before rushing into a CPU upgrade.

Just a heads up—some people have found that the B660m doesn't have the greatest VRMs for overclocking, and since it’s DDR4, I'd advise against upgrading the CPU while keeping the same motherboard. It might be worth considering a whole new setup if you want to really maximize your performance.
