I have a Crosshair VI, a 1700X and 4x16GB Samsung B-die ECC. I need to (a) upgrade to 3900X and (b) use the 1700X for my home server. So I will need a MB (I already have some cheap RAM). The prices on X570 are insane. But, I can afford it if necessary/worth it. I see the following options:
1. ROG Strix X570-E ($350 local price)
2. ROG Strix X470-F ($200 local price)
3. Put the 3900X on the Crosshair VI and buy a cheap B450 for the home server ($150 local price).
I want ASUS because I know they have ECC support (tested and works on my Crosshair VI).
What would you do?
