I mainly game at 1440p and currently have a Ryzen 5 5600, Radeon RX 6800 XT, and 16GB of DDR4. My original upgrade plan was a Ryzen 7 5800X3D for about $370, a Radeon RX 9070 XT for $810, and 32GB of DDR4 for around $260. I need new memory because my current setup uses four 4GB sticks.
The Ryzen 7 7800X3D costs about $320 where I live, but moving to AM5 would make the platform roughly $300 more expensive because 32GB of DDR5 costs around $460. The comparisons I have found show the 7800X3D being roughly 10–15% faster than the 5800X3D in general, with the difference increasing to around 20–30% in CPU-heavy games.
I would like to keep the upgraded system for four or five years. Since I probably would not upgrade the CPU again during that time, is the extra $300 for the 7800X3D and AM5 platform worthwhile? I play a wide range of games, including demanding titles such as Spider-Man 2, STALKER 2, Kingdom Come: Deliverance 2, and DayZ. I do not play many competitive shooters, but I do have a 144Hz monitor and appreciate high frame rates. Should I stay on AM4, move to AM5, or keep the Ryzen 5 5600 for now?

If you are definitely keeping the system for four or five years and can comfortably afford the platform premium, AM5 is the more future-proof choice. The 7800X3D gives you more CPU headroom in simulation-heavy and poorly optimized games, and the faster platform should age better. That said, the 5800X3D is still an excellent gaming CPU, so this is mostly a question of how much you value the extra margin rather than whether AM4 would be inadequate.
The Ryzen 5 5600 is still capable of handling most 1440p gaming. For games such as STALKER 2, Kingdom Come: Deliverance 2, or heavily populated DayZ servers, a faster X3D processor can help with frame-time consistency, but the improvement depends heavily on the specific scene and settings.
You could also consider a non-X3D Ryzen 5 processor on AM5 if it is substantially cheaper in your region. It would give you the newer motherboard and memory platform without spending as much on the CPU, and you could upgrade later if a future game actually exposes a CPU limitation. Another option is to sell your existing CPU, board, and memory, which could reduce the effective cost of switching.
The simplest way to look at it is that the 5800X3D is already a major step up from the Ryzen 5 5600, while the 7800X3D is another improvement on top of that. The newer chip is most valuable if you care about consistently high minimum frame rates in CPU-heavy games. If your games are mostly GPU-limited at 1440p, you may barely notice the difference during normal play, making the extra $300 difficult to justify.
At 1440p, the graphics card will usually be the limiting part, especially with a high-end GPU running demanding games at high settings. I would prioritize the 9070 XT first. Your 16GB of RAM is still usable for gaming unless you regularly play heavily modded games or memory-hungry simulations, so you could postpone the CPU and memory platform upgrade until prices improve.
I play a bit of everything, including demanding AAA games like Spider-Man 2, STALKER 2, and Kingdom Come: Deliverance 2. I also play some DayZ. I do not focus on competitive shooters, but I still like taking advantage of my 144Hz monitor.
