I'm considering buying a used Intel i5-13600K for €180 to improve performance in Rust. I'd like to keep my existing 32GB of DDR4-3600 CL16 memory, so AM5 and other platforms are less appealing unless there's a clearly better-value option. I'm based in Latvia, so local CPU pricing may affect the recommendation. My current system has an i5-10400F, 32GB DDR4-3600 CL16, and a Radeon RX 6950 XT. Is the 13600K a worthwhile upgrade for the money, or is there a better DDR4-compatible choice?

At €180, the 13600K is probably one of the strongest value upgrades that lets you keep your DDR4 setup. Compared with the 10400F, it should provide a noticeable improvement in CPU-heavy games, including better minimum frame rates in Rust. Just make sure your motherboard supports it with a BIOS update and that your cooler and power delivery are adequate.
A Ryzen 5 5500X3D around €200 could be worth checking, but it depends on the exact local price and whether you already have an AM4 board. If you would need a new motherboard, the 13600K is likely the more practical purchase. The regular Ryzen 5 5500 is a much weaker option and isn’t really comparable to the 13600K.
Rust can still have inconsistent performance even on fast hardware, so don’t expect any CPU to make every situation run perfectly. However, the 13600K should still be a substantial step up from the 10400F. Some game settings and configuration tweaks may also help if you’re dealing with stutters or poor frame times.
There are newer performance options and experimental graphics features that can help in some cases, but they won’t change the fact that Rust can be unusually demanding and poorly optimized. I wouldn’t replace the entire PC just for this one game.
The price looks good, especially since you already have DDR4-3600 CL16 memory and a powerful RX 6950 XT. Moving to AM5 would also mean replacing the motherboard and RAM, so the total platform cost would be much higher. I’d only skip the 13600K if you find a much cheaper compatible CPU or are planning a full platform rebuild soon.
The 5500 is based on an older design and generally doesn’t offer the same performance level as the 13600K. It only makes sense if it’s available very cheaply or you already own a compatible AM4 motherboard.
