I'm in my 40s and don't have much time for gaming or editing, so I'm not trying to build a high-end system. I'd like to spend roughly $500, or up to about $600 in local European pricing, on upgrades that provide noticeable improvements.
The PC is used for 1080p gaming, light multimedia editing, coding, movies, and music. It currently has a Gigabyte Z170 MX Gaming 5 motherboard, an i5-6600K, 32GB of DDR4 memory, an RX 6600 8GB, a 120GB operating-system SSD, a 3TB SSD, and a 3TB hard drive. The RX 6600 handles all the games I play, so I'm not particularly interested in replacing it right now.
The i5-6600K seems like the biggest performance limitation, especially in CPU-heavy strategy and simulation games. I've considered a modern Ryzen 7 X3D processor, but I realize that may require a new motherboard and DDR5 memory. I could also add more RAM, replace the remaining hard drive for reliability, or replace the unknown 10-year-old Bronze-rated power supply. The current Hyper 212 cooler also runs above 90°C while gaming, although it has not had fresh thermal paste in several years.
Given this hardware and budget, what would you upgrade first, and why?

A Ryzen 7 9800X3D is not compatible with your current board or DDR4 memory. It uses AM5, so the upgrade would require the processor, an AM5 motherboard, DDR5 RAM, and probably a new cooler. That would consume most or all of the budget before addressing anything else.
A cheaper route would be an AM4 Ryzen 7 5700X3D, a suitable AM4 board, and reuse your existing DDR4. Depending on local prices, that could fit around $400–$500 and would be a major improvement for simulation and strategy games. Check your memory speed first; DDR4-2666 is usable, but DDR4-3200 or faster would be preferable.
I’d keep the RX 6600. At 1080p it’s still a sensible card, and replacing it would probably give you less benefit than fixing the CPU bottleneck in the games you play.
One possible value build is an Intel 12700K or similar processor with a compatible motherboard. In some markets, the CPU and board together can cost around $300, leaving room for a cooler or storage. You could also sell the old CPU and motherboard to reduce the effective cost. I would only replace the graphics card if you actually run into games where the RX 6600 is no longer sufficient.
Before spending on more RAM, I’d replace the thermal paste and identify the power supply. A 10-year-old PSU is a bigger reliability concern than having only 32GB of memory, and an 850W unit is unnecessary for an RX 6600 unless you plan a substantial graphics upgrade later. A good 550–650W model from a reputable manufacturer should be enough for this system.
Replacing the old hard drive with another SSD is also worthwhile if the drive contains important data, but it won’t improve game performance much. Keep backups regardless, since replacing one drive does not protect against data loss.
