ASUS TUF Gaming X870-Plus WiFi: This is presented as a top pick, offering a unique industrial design, ample high-speed I/O, fast networking, and widespread PCIe 5.0 support. It's considered a good match for the Ryzen 7 9800X3D as a powerful yet affordable CPU.

The MSI MAG X870 Tomahawk WiFi is a robust AM5 motherboard designed for gamers seeking high connectivity and performance. It features an impressive array of USB ports, including two 40 Gbps USB4 Type-C connections, and supports Wi-Fi 7 for fast wireless networking. The motherboard accommodates up to 256 GB of DDR5 RAM, with speeds reaching 8400 MT/s, and offers multiple PCIe slots for expansion. However, it has limited high-speed PCIe and M.2 configurations, which may deter users needing extensive expansion options. Overall, it provides excellent value for a mid-range gaming setup, priced around $299

ASRock X870E Taichi is my suggestion.
