I'm considering upgrading from my Ryzen 5 3600 because CPU prices are more reasonable than GPU prices right now. My motherboard is a Gigabyte B450M DS3H WiFi, and the person who built my PC warned me that its relatively modest 4+3-phase VRM and small heatsinks may not be ideal for higher-power Ryzen processors. They suggested treating the Ryzen 5 5600X as the safer limit, while saying a Ryzen 7 5700X3D or 5800X3D should probably work because those chips have lower power limits than the regular 5800X or 5800XT.
My main use is gaming with Discord and OBS running, plus some Blender work. I have 32GB of DDR4-3200 CL16 memory, a Corsair RM750e power supply, and an RX 6600. I may upgrade the GPU later, but I plan to stay on AM4 for a while. I'm aiming for good value and would prefer to keep the CPU under about $400.
Would this motherboard safely support a Ryzen 7 5700X3D or 5800X3D without replacing the board? Would a Ryzen 5 chip be a better match for my current GPU, and what BIOS, cooling, airflow, or power-limit considerations should I keep in mind?

Your 32GB of DDR4-3200 CL16 is perfectly reasonable for AM4, and the 750W power supply is more than enough for the CPU and RX 6600. Replacing the motherboard with a B550 model is optional rather than required. It could provide stronger VRMs and newer features, but it will not dramatically improve CPU performance by itself. Put that money toward the CPU cooler or a future GPU unless you specifically want better connectivity or expansion options.
The biggest question is whether the upgrade is worthwhile with the current graphics card. At RX 6600 performance levels, many games will remain GPU-limited, so a 5700X3D may not show its full advantage immediately. You should still notice better minimum frame rates and smoother performance in CPU-heavy games, especially while streaming or running background tasks. If your current games already run well, saving for a future GPU may provide the larger overall improvement.
You do not automatically need a new motherboard just because you are moving from Ryzen 5 to Ryzen 7. The important factors are CPU support in the BIOS, VRM cooling, case airflow, and the workload. I would avoid a regular 5800X or 5800XT on that board for long, sustained all-core workloads unless you are willing to power-limit it. A 5700X3D or 5800X3D is a much more sensible ceiling for the existing board.
The 5700X3D is probably the best value upgrade for this system. It gives you eight cores and the gaming benefits of 3D V-Cache without the relatively high power draw of the standard 5800X. The 5800X3D is also compatible in principle, but it usually costs more while offering only a modest performance difference over the 5700X3D. Use a proper tower cooler rather than the original Ryzen 5 3600 cooler, update the motherboard BIOS before swapping CPUs, and enable the memory’s XMP/DOCP profile afterward.
For gaming, the motherboard is probably fine with a 5700X3D or 5800X3D, provided the BIOS supports it. Those CPUs generally draw much less power in games than a regular 5800X or 5800XT, often landing around the 60–80W range depending on the title and settings. The VRM becomes more concerning during sustained all-core workloads, such as long Blender renders, where temperatures may rise and the CPU could reduce its clocks. Make sure the case has decent airflow and monitor the VRM or motherboard temperature if the board exposes that sensor.
With the RX 6600, a Ryzen 5 5600 or 5600X would already be a substantial upgrade from the 3600 for much less money. The X3D chips make more sense if you want to keep the platform for several years or plan a much faster graphics card later.
