Coincidence that you and I have almost similar PCs build.
I upgraded from my AMD AM3+ Motherboard and Processor to Ryzen 3700X and Asus TUF Gaming X570 Pro (WiFi) motherboard,
Originally I had purchased from Amazon the same Asus Motherboard you have (Crosshair VIII) but it was DOA and the replacement from Amazon was almost 2 years old which I sent it back without using.
Asus Support said the old Asus Motherboard will only have about 2 1/2 years of Warranty instead of 3 years by the Serial Number that I gave them.
But then I found out about the TUF Gaming X570 Pro that came out in September 2020 and it has almost the same features as the more expensive Crosshair VIII Wifi Motherboard.
Both have 8 SATA Ports, 4 PCIe Slots, WiFi, Supports the latest AMD Processors, and most important it has the BIOS FLASHBACK feature.
The only diffence is the VRM is probably much stronger in the Crosshair VIII than in the Pro motherboard but otherwise it has almost identical features for about $170.00 less.
