I currently have an i3-9100F, 16GB of slow DDR4, and an RTX 4060. My MSI B360-A PRO can apparently be upgraded as far as an i9-9900K, but I'm unsure whether that makes sense or if I should replace the platform entirely. My current options are a used i9-9900K for 800 PLN, a Ryzen 7 5800X3D with a motherboard and 32GB of DDR4 for 1,600 PLN plus a cooler, or a new Ryzen 5 9600X with a motherboard and 16GB of DDR5 for about 2,500 PLN. The 32GB kit in the 5800X3D bundle is four 8GB sticks with an overclocked 1:1:1 memory configuration. I mostly play League of Legends and CS2, but games like Arma 3 and War Dogs are exposing the limits of my current CPU. Is the 5800X3D still the best value, or should I spend more on AM5 for a future upgrade path? I also need to verify the exact model of my 500W power supply.

The 9600X gives you the better long-term platform because AM5 should support future CPU upgrades, but 2,500 PLN is a lot more, and one 16GB DDR5 stick is a bad configuration. You would want a matched 2x16GB kit for proper dual-channel performance. If you choose AM5, a Ryzen 5 7500F or 7600, paired with 32GB of DDR5, could offer better value than the 9600X while leaving room for a future upgrade.
The 5800X3D is the strongest value among those three choices. It should be roughly 30% faster than the 9900K in many games, uses less power, and the bundled motherboard and 32GB of memory make the price very attractive. A Thermalright Phantom Spirit or another decent dual-tower cooler should be enough. Just make sure the motherboard and CPU are healthy and that the seller’s BIOS settings are stable.
The 1:1:1 setting simply means the Ryzen memory controller, Infinity Fabric, and RAM are running in sync. It can provide a small performance improvement, but it is not a major selling point, especially with four memory sticks. I would reset the BIOS and test the system yourself rather than blindly using a profile from a USB drive.
I would skip the i9-9900K at 800 PLN. It is still an improvement over the i3, but the price is difficult to justify for an old, power-hungry platform with no meaningful upgrade path. Before buying anything, check the exact model and condition of your 500W power supply. It may run an RTX 4060, but an unknown or low-quality unit is worth replacing rather than trusting with a new build.
I would only choose AM5 if you can comfortably afford the extra cost and plan to upgrade the CPU later. Otherwise, the 5800X3D bundle will deliver excellent gaming performance now, particularly in CPU-heavy games like Arma.
