Should You Buy It?

Recommended for the right buyer

The Core i5-12600K remains a top-tier choice for enthusiasts and gamers in 2024. If you want a CPU that can handle any game and moderate content creation without bottlenecking modern GPUs, this is it. Ensure you pair it with a Z690 or Z790 motherboard to utilize overclocking, and invest in a quality cooler, as it runs hot under load. If you don't plan to overclock, the i5-12600K or i5-13600K offer similar value, but the 12600K is cheaper. Avoid if you are building a strictly budget system.
