My current system has a Ryzen 5 5600X, MSI MAG X570S Tomahawk Max motherboard, 32GB of DDR4-3600 CL16 memory, an RTX 3080 12GB, an 850W power supply, and a 27-inch 1440p monitor. It still handles most of my games well, but I notice some limitations in more demanding titles such as Helldivers 2, BeamNG, and Forza Horizon 6, especially when increasing graphics settings. I also want to try Cyberpunk 2077 and Battlefield 6.
I would prefer to extend the life of this AM4 system rather than build an entirely new PC while hardware prices remain high. A local retailer currently has the Ryzen 7 5800X3D on sale, and a $50 coupon would bring the price down to $250. I could also sell my 5600X afterward.
Would I see a noticeable improvement in these games, particularly in frame-time consistency and 1% lows? Is spending roughly $250 minus whatever I get for the 5600X a worthwhile way to keep this system going for several more years?

That is an excellent price for a new 5800X3D, and it is probably one of the last opportunities to make a major upgrade without changing your motherboard, memory, and platform. With an RTX 3080 at 1440p, the extra cache should help keep demanding games smoother. If your cooler is adequate, you may be able to reuse it, but remember to check your BIOS settings after the swap and re-enable the memory profile and fan curves if they were reset.
At $250, the 5800X3D is a very strong upgrade for this system. You only need to replace the CPU, and selling the 5600X offsets part of the cost. BeamNG and Forza should benefit noticeably, while Helldivers 2 and Cyberpunk can also improve in CPU-heavy areas. The biggest difference will often be smoother frame times and better 1% lows rather than a huge increase in average FPS.
The main argument against it is that the cores are still on an older platform. If you were already planning a new graphics card and a complete rebuild soon, putting that money toward an AM5 system could make more sense. But for your stated goal of avoiding a full rebuild and getting a few more years from the current PC, $250 minus the resale value of the 5600X is easily justifiable. A 5800X3D should also be a better long-term gaming upgrade than moving to a regular higher-core AM4 chip.
I would not count on getting an unusually high price for the 5600X, since newer platforms have become more competitive. Even without a large resale return, though, the 5800X3D deal is still compelling if you want to stay on AM4.

Cyberpunk can show especially large gains in busy CPU-limited areas such as Dogtown or crowded city sections, so it is not limited to just a minor improvement.
