I'm still using an AM4 motherboard and would rather upgrade within that platform than move to AM5. My current Ryzen 5 3600 is holding back my graphics card, so I'm looking for a stronger gaming CPU. I have 16GB of RAM and mainly play single-player games, although I occasionally play CPU-heavy titles such as Deadlock and Dota 2. I'm considering the Ryzen 5 5500X3D, Ryzen 7 5700X, or possibly another AM4 option. Which processor offers the best value for 1440p gaming with a Radeon 9070 XT, and what else should I consider? I'm not very experienced with PC hardware, so a straightforward explanation would be appreciated.

A 5700X is also a good, affordable upgrade, especially if you can find one noticeably cheaper than an X3D processor. Enabling Precision Boost Overdrive can improve performance, but you do not need to manually overclock it. PBO is generally safer and simpler than experimenting with fixed voltage and clock settings, provided your motherboard and cooling are adequate.
For gaming, the Ryzen 5 5500X3D is probably the best value if it is priced reasonably where you live. Its extra 3D V-Cache can improve frame rates and reduce stuttering in many games, while the two additional cores on a 5700X usually do not make a huge difference in gaming. It should be a major upgrade over the Ryzen 5 3600 and a sensible match for a 9070 XT at 1440p.
The 5500X3D makes the most sense if your priority is games. If you also do heavier productivity work, the extra cores on a 5700X become more useful.
The 9070 XT and a 5500X3D should work well together at 1440p. You may still encounter a CPU limit in particularly demanding simulation games or when targeting very high refresh rates, but that does not mean the graphics card will be unusable. Also consider moving from 16GB to 32GB of DDR4, since newer games can occasionally run more smoothly with the extra memory.

Manual overclocking is not required here. The system is very unlikely to suddenly fail from normal PBO settings, but monitor temperatures and avoid blindly increasing voltage.
