For 12600K, the MSI Pro-A is a good enough.

The ASUS ROG STRIX Z790-A Gaming WiFi is my top pick if budget isn't a major concern. Excellent build quality, great power delivery for overclocking, WiFi 6E, and that classic ROG aesthetic. Yes, it's pricier than some alternatives but worth it for the feature set.

I've been using the ASUS TUF Gaming Z690-Plus WiFi D4 with my 12600K, and it's been great. It has good VRMs for overclocking, WiFi 6, and supports DDR4 RAM if you want to reuse your existing memory. Plus, the BIOS is user-friendly. Definitely worth considering!

For most users, the ASUS PRIME Z790-A WIFI offers the best balance of features and price. It supports DDR5 RAM up to 7200MHz and has PCIe 5.0 for GPUs, making it somewhat future-proof. While you won't fully utilize the memory speeds with the 12600K (it maxes at 4800 MT/s), this leaves room for future CPU upgrades.

For enthusiasts with deeper pockets, the ROG Maximus Z790 DARK HERO is the premium choice. Its 20+1 power phase design is excellent for overclocking, and it has high-end features like Thunderbolt 4 ports. However, it's significantly more expensive.

Budget-conscious builders should consider the MSI B760 Gaming Plus WiFi. Despite being a micro-ATX board, it offers surprisingly good performance and can support up to 256GB of DDR5 RAM. The 12+1+1 power design is decent for moderate overclocking.

All three boards use the LGA 1700 socket and support 12th-14th gen Intel processors, so you have upgrade flexibility. Just make sure your case can accommodate the form factor you choose (especially for the micro-ATX B760).
