My current gaming PC has a Ryzen 5 5600X, Radeon RX 9070 XT, 32GB of DDR4-3600, and an ASUS TUF Gaming B550-PLUS WiFi II motherboard. I mainly play demanding games such as Total War and Monster Hunter, usually at 1440p. I want to keep this system for several years, but I do not want to replace the motherboard, so any upgrade would need to remain on the AM4 platform. Would upgrading the CPU noticeably improve performance, and which AM4 processor would make the most sense?

The Ryzen 7 5700X3D or 5800X3D would be the meaningful AM4 upgrades for gaming. The extra 3D cache can improve average FPS, eliminate some stutter, and raise minimums, but the benefit depends heavily on the game. In some titles you may see little change, while CPU-heavy games can gain roughly 20–40% at 1440p. The 5800X3D is the fastest AM4 option, though the 5700X3D is often the better value if it is substantially cheaper.
Before buying a 5800X3D at a high price, compare it with the 5700X3D and consider the cost of moving to AM5 after selling your current CPU, board, and memory. A newer platform gives you a longer upgrade path, but if you want to keep the B550 system, an X3D chip is the sensible endpoint. Avoid upgrading to a regular 5700X or 5800X solely for gaming unless it is extremely cheap, since the improvement over the 5600X is usually modest.
I would prefer not to replace the motherboard, so I will compare current 5700X3D and 5800X3D prices first and check my GPU usage in the games I play.
At 1440p, the 9070 XT will often be the main limit, especially with demanding settings, so a CPU upgrade is not automatically necessary. Check your GPU utilization while gaming: if it stays close to 95–100%, the graphics card is doing the limiting; if it drops well below that while one or more CPU threads are maxed out, the 5600X is holding things back. Total War and other simulation-heavy games are more likely to benefit than straightforward GPU-bound games.
That is why the answer varies so much between games. A 5600X can be perfectly fine in one title but cause lower minimums or stutter in a large open-world or strategy game.
I play at 1440p, so I was unsure whether the GPU would usually be the limiting factor. The CPU-heavy games and better minimum FPS are what interest me most.
