My current PC runs Windows 11 on an ASUS ROG STRIX B550-F motherboard with a Ryzen 5 3600, GTX 1650 Super, 64GB of DDR4 RAM, and a 1TB NVMe SSD. It still performs reasonably well, but World of Warcraft starts stuttering, lagging, and occasionally freezing or shutting down when large raid encounters involve lots of spell effects. I mainly want to optimize this system for smooth WoW gameplay rather than newer games at high settings, and I would prefer upgrading instead of building a whole new PC. Would a Ryzen 7 5800X3D and RTX 4060 be appropriate, or would a cheaper Ryzen 5 5600X3D be enough?

The 5600X3D is a great fit and WoW is unlikely to benefit much from the extra cores in a 5800X3D. Your GTX 1650 Super may still be adequate if you lower settings such as shadows and spell effects, so I would prioritize the CPU first. Consider a GPU upgrade only if you also play more graphics-heavy games.
A 5500X3D or 5600X3D paired with a used RTX 3060 12GB would be a cost-effective option for 1080p. That would be a substantial improvement without replacing the motherboard, RAM, or storage. Check motherboard BIOS support before installing the new CPU.
A 4060 combined with a 5600X3D would handle WoW raids well, but the CPU upgrade is the more important part for the specific stuttering problem. Before buying anything, monitor CPU and GPU usage during a raid and check temperatures. Also investigate the shutdowns separately, since a properly functioning system should not power off just because a raid is busy.
WoW is usually much more CPU-sensitive than memory-sensitive, especially during raids. An X3D processor would be a strong upgrade on your existing AM4 platform, and a 5600X3D should already be plenty for WoW. You can upgrade the graphics card later if performance is still lacking; the two upgrades do not need to happen together.
Would I need a different CPU cooler for one of those processors?
The freezes and shutdowns deserve attention on their own. Check Windows Event Viewer for critical errors, monitor CPU and GPU temperatures, verify that the power cables are secure, and run a memory and storage check. Sudden shutdowns can point to overheating, power delivery, unstable settings, or a failing component rather than simply insufficient gaming performance.

Would the stock cooler be sufficient, or should I buy a better one?
