I have not built a new rig from the ground up for about 5 years. It is time and I have 99% decided to go with AMD for the first time. I am waiting for the 3950X since the 3900's are sold out anyway.
I am considering a Gigabyte X570 Master Mobo instead of ASUS this time (had just to many component quality issues with ASUS stuff over the last few years)
For memory I am considering Corsair Dom Plat 32Gb but I am not sure if it matches the other components well.
I guess my problem is that after my last build I did not stay up on all the improvements and changes so I find myself asking questions and learning all over again.
This thread is helpful for sure.
