I recently bought a prebuilt with an Intel i5-14400F, Radeon RX 6800, ASRock B760 Pro motherboard, 32GB of DDR4-3600 memory, a Thermalright Aqua Elite 360 AIO, and a 750W Seasonic Platinum power supply.
At 1080p, some games seem to hit a CPU limit. In Slime Rancher 2 at 120 FPS with maximum settings, GPU usage is only around 40–50% while the CPU sometimes appears to reach 100%, and the 1% lows feel rough. Subnautica 2 is even less comfortable. Limiting the frame rate to 60 FPS makes the experience much smoother.
Would upgrading from the 14400F to a 13600K or 14600K be worthwhile, or is there a better-value LGA1700 processor that would handle a steadier 120 FPS? Current-generation Ryzen processors seem more attractive, but I cannot afford to replace the motherboard, CPU, and RAM right now. XMP is enabled, I am using two 16GB sticks, and CPU temperatures are around 50°C. What would you do?

A 13600K or 14600K would be an upgrade, but the improvement probably is not large enough to justify spending several hundred on an LGA1700 replacement. You would also need to check BIOS support and power limits, and the 14600K can run considerably hotter than the 14400F. The 14400F is still a good processor, so I would only upgrade if you can find a clearly discounted used chip or sell the existing one for a good price.
The 14400F should generally be capable of running these games well, so I would investigate the stuttering before buying a new CPU. Check Task Manager and a proper monitoring tool while the game is running, because the Steam overlay’s CPU figures can be confusing. Also verify that the game is installed on a fast SSD, check background processes, and monitor individual CPU-core usage rather than only the overall percentage.
A drop or brief freeze while moving between areas sounds more like asset or world streaming than a constant CPU limitation. A perfectly locked 120 FPS is not guaranteed, even if the average frame rate is close to 120. Try a frame cap around 100–117 FPS, or use adaptive sync if your monitor supports it; that can make occasional dips much less noticeable.
If you absolutely need more performance without changing platforms, a 14600K or 14600KF is the sensible step up. A 12600K would not be a meaningful upgrade from a 14400F, and moving to a 14700K is difficult to justify for this system. For a truly noticeable gaming improvement, especially in CPU-limited games, an AM5 system with a modern 3D-cache Ryzen chip would be the better long-term route, but that means replacing the board and memory too. I would troubleshoot the freezes first and keep the 14400F for now.
XMP is enabled and I have 2x16GB. Temperatures are about 50°C. The farm area stays around 114–120 FPS with a 120 cap, but I get a brief freeze when moving between areas every 30–40 seconds. It does not happen at 60 FPS, so I suspect the game may be loading in more of the world.
