I currently have a Core i5-12600K, 32GB of DDR4 memory, a B760 motherboard, and an RTX 4070 Super. I mainly want comfortable 1440p gaming and the option to play some titles at 4K. Because DDR5 and new-platform prices are high, I would prefer to keep my current motherboard and memory and spend around $350 on a processor upgrade instead. I was considering a Core i7-14700K, although I'm not sure whether my B760 board, cooling, and power delivery are suitable. Would this provide a noticeable gaming improvement, or are there better LGA 1700 options?

I went from a 12700K to a 14700K with the same 4070 Super at 1440p and barely saw an FPS difference. The upgrade was more noticeable in simulation and other CPU-heavy games. If you find a 14700K on a very good sale, it can make sense, but it runs hot and uses substantially more power. Make sure the motherboard has an appropriate BIOS update and that your cooler can handle it; also use sensible power limits rather than assuming any B760 board is ideal for an unrestricted 14700K.
The 12600K and 4070 Super are already a well-balanced combination for 1440p. If the GPU is maxed out at your target settings, the practical upgrade would eventually be a faster graphics card, not a processor. For CPU-limited situations, lowering resolution or graphics settings usually makes the CPU bottleneck easier to identify; if FPS barely changes while GPU usage falls, then a faster CPU could help.
Your B760 motherboard can support 14th-generation processors after a BIOS update, but it cannot overclock a K-series CPU. A 14700F or 13700/14700 non-K model may be better value if you find one cheaply, though the 14700K can still run at stock settings. Before upgrading, check whether the specific games are CPU-limited. Frame drops in crowded open-world scenes can be CPU-related, but storing the game on an NVMe drive mainly helps loading and streaming—not CPU performance.
At 1440p and especially 4K, the RTX 4070 Super will usually be the limiting component, and the 12600K is already plenty capable. Check GPU usage while playing with an overlay: if the GPU is consistently around 90–100%, a CPU upgrade probably won’t raise average FPS. Look at CPU usage and per-core utilization during the frame drops instead. Also, the 14700K is an i7, not an i5.
That makes sense. I’d only consider it at a substantial sale price rather than buying it at the current price.
