My current system has a Ryzen 5 5500, Radeon RX 6700 XT, 32GB of DDR4-3200 CL16 memory, a B450 Aorus Elite V2 motherboard, and a 650W PSU. I play at 1080p and 144Hz, and the CPU is already limiting performance in some games where I would like to stay closer to 120 FPS.
I originally considered the Ryzen 7 5800X3D as the only worthwhile AM4 upgrade, but it costs around 8,500 CZK (roughly $400) in my country, and used prices are not much better. The Ryzen 7 5800X and 5800XT are closer to 5,000 CZK, so I am wondering whether either would provide a meaningful gaming improvement over the 5500. I am also considering waiting a couple of years and moving to a newer platform instead.
How do the Ryzen 5 5500, Ryzen 7 5800X/5800XT, and 5800X3D compare specifically in gaming? Would a cheaper option such as a 5600-series chip or 5500X3D make more sense? Finally, would my 650W power supply be sufficient for a CPU upgrade, or should I plan to replace it?

Your 650W PSU should be fine for a CPU upgrade. A Ryzen 7 chip does not add enough power draw to require an immediate replacement, especially with the RX 6700 XT. Make sure the PSU is healthy and properly connected; undervolting the GPU is an optional extra, not something you should need just because you move to a 5800X-class processor.
A newer platform is another option if the price of the 5800X3D is close to a complete upgrade. A modern midrange CPU and motherboard may offer better value and an upgrade path, especially if you can reuse your DDR4 memory. However, replacing the platform solely for GTA 6 speculation may not be worthwhile until the PC requirements and performance are known.
The regular 5800X and 5800XT are not especially compelling gaming upgrades. They add cores, but most games will not benefit much from them, so the improvement over a 5500 is usually modest. A Ryzen 5 5600, 5600X, or similar chip can provide a noticeable generational improvement for less money, while an X3D model is the more meaningful high-end AM4 gaming upgrade.
If you can find a 5500X3D at a reasonable price, it is worth considering. The extra cache can improve CPU-limited gaming performance substantially, although its lower clock speed means it is not an upgrade for general productivity work. The 5800X3D is faster still, but at around $400 it is difficult to justify unless you specifically want to keep the current motherboard for several more years.
For gaming only, I would either move to a 5600-class CPU and save the money, or keep the 5500 until you are ready for a full platform change. Going from a 5600 to a regular 5800X or 5800XT generally gives only a small gaming gain unless a particular game benefits from the additional cores. Check your GPU usage and frame-time data first so you know whether the CPU is actually the limiting part in the games you play.
