Does this motherboard support AM5 CPUs?

Yes it does, I use it with Ryzen 7 7700. Best to set the cpu fan profile so that 100% fan speed at 60 C, if you use stock cooler from AMD (cpu with fan box).

How does the gaming performance at 1080p of the MSI PRO B850-P WIFI R compare to the ASUS PRIME B850-PLUS WIFI motherboard?

Gaming performance at 1080p between the MSI PRO B850-P WIFI and the ASUS PRIME B850-PLUS WIFI will be very similar since they both support the same AMD Ryzen 7000/8000/9000 processors and DDR5 memory. The MSI board's PCIe 5.0 support might give a slight edge in future-proofing with faster graphics cards, but for current mid-range GPUs, the difference in frame rates at 1080p will be negligible. If you're looking for features beyond raw gaming FPS, the MSI board offers Wi-Fi 7 and 5G LAN, which could provide better network performance for online gaming. Meanwhile, the ASUS board might have different BIOS or cooling solutions that affect stability and overclocking potential slightly, so picking based on your full system needs is worthwhile.
