I've ordered a Ryzen 7 5800X3D and plan to stay on AM4 for now rather than replace the entire platform with AM5. My current system has a Ryzen 5 1600, GTX 1660 Super, 16GB of DDR4-2133 memory, a Cooler Master 500W Bronze PSU, and a damaged Asus PRIME A320M-K motherboard that can lose video and disconnect USB devices whenever the desk is bumped. I'll need a replacement motherboard, preferably a reasonably priced B550 model with Wi-Fi and Bluetooth, plus a new CPU cooler because I'm still using the stock cooler from the Ryzen 5 1600. I'm considering a Thermalright Burst Assassin 120 EVO Dark and want to know whether it's sufficient for the 5800X3D. I'd also like advice on whether my slow memory will noticeably limit the new processor, whether upgrading to 32GB of DDR4-3600 can wait, how long the 500W PSU should be suitable with the 5800X3D and GTX 1660 Super, and what GPU tier would make sense as a future upgrade.

It’s worth looking at the total cost before committing to AM4. You’re replacing the motherboard, possibly replacing the RAM, and buying a premium last-generation CPU. The 5800X3D is a great drop-in upgrade when you already have a suitable AM4 board and decent memory, but in your case an entry-level AM5 setup could make more sense if the price difference is manageable. Otherwise, stay with AM4, buy a solid B550 board, use a capable dual-tower cooler, and postpone the RAM upgrade until you replace the GPU.
For a balanced future build, prioritize the graphics card after the platform repairs. The 5800X3D is powerful enough for cards well above the GTX 1660 Super, so there’s no need to match it with a modest GPU immediately. Just check the replacement card’s power requirements before upgrading the PSU; the current 500W unit is suitable for the existing setup but may not be ideal for higher-end GPUs.
Most B550 boards should handle the 5800X3D without trouble, since it isn’t an especially high-power CPU. Make sure the board’s BIOS supports it, especially if buying older stock. Your 500W PSU should also be fine for now; the 5800X3D and GTX 1660 Super together should stay well below its practical capacity. The DDR4-2133 memory will leave some performance on the table, but the large 3D V-Cache reduces the impact compared with a normal CPU. You can try enabling an XMP/DOCP profile or manually overclocking it, but a memory upgrade isn’t urgent. A dual-tower cooler would be preferable because the 5800X3D tends to run warm, although a good single-tower cooler can work if case clearance is limited.
Since you’re currently using a GTX 1660 Super, you may be GPU-limited in many games. A cheaper AM4 X3D chip paired with putting the savings toward a graphics card could deliver more noticeable gaming performance than a 5800X3D while keeping the 1660 Super. A used RTX 3070-class card, for example, would be a much larger upgrade than moving from the Ryzen 5 1600 to a faster CPU while keeping the same GPU.
Undervolting the 5800X3D is also worth considering. It can substantially reduce temperatures and power use while maintaining, or sometimes improving, performance.
