I currently have a PC with a Radeon RX 7800 XT, Ryzen 5 5600G, Corsair 360mm cooler, 32GB of G.Skill 3200MHz RAM, an ASUS B550-F Gaming motherboard, and a Corsair RM850x power supply. I mainly play AAA games at 1440p ultrawide on high settings. I can buy a brand-new Ryzen 7 5800X3D 10th Anniversary Edition for €350, and I'm wondering whether it's a worthwhile upgrade for maximizing my AM4 system or whether I should keep the 5600G and save for a future platform upgrade.

Before buying, check whether you are actually CPU-limited. Monitor GPU usage and frame rates in the games you play: if the GPU is near 99% usage, a CPU upgrade won’t add many average FPS, though it may still improve stuttering and 1% lows. Faster memory, such as a well-tuned 3600MHz CL16 kit, could offer a small improvement, but it probably isn’t worth replacing your current RAM just for that.
If you want to keep this AM4 system for several more years, the 5800X3D makes sense as a final upgrade, especially since you already have a capable cooler, motherboard, RAM, and power supply. At €350, though, I’d only buy it if you’re regularly seeing CPU limits or poor frame times. Otherwise, keep the 5600G and put the money toward a future CPU, motherboard, and DDR5 upgrade.
The 5800X3D is the best gaming upgrade you can make without replacing the motherboard and moving to DDR5. It should improve CPU-limited performance and especially your 1% lows, making games feel smoother. Your 7800 XT is powerful enough that the 5600G may hold it back in some titles, although at 1440p ultrawide you’ll still often be GPU-limited.
€350 is fairly expensive for a 5800X3D. The performance increase is often around 20–30%, and the difference will be much smaller when your graphics card is already running at full utilization. At that price, you should compare it with a cheaper 5700X3D, 5600X3D, or 5500X3D if any are available. Otherwise, saving for a complete AM5 upgrade could provide better long-term value.
The 5600G is a weaker gaming CPU than a regular 5600 because it has less cache, so moving to a newer eight-core chip would be a noticeable improvement. Even a reasonably priced Ryzen 7 5700X or 5800X could help, though the X3D models are generally better for gaming and frame-time consistency.

A used 5700X or 5800X can be a good middle ground if the 5800X3D is too costly. It won’t match the X3D chip in every game, but it should still be a substantial step up from the 5600G.
