Hi Daniel,

I went all AMD on my build from late last year.  There were a couple of 
teething issues in the first few months, but all have been sorted out by 
early this year.  I'm running a 3900X and 5700XT.  I'm not really fussed 
on PCIe 4 for graphics performance at the moment, but I have 2 x NVME 
gen4 SSDs in RAID 0 (mdadm), and they don't compete for bandwidth with 
the GPU.  I can also swap out the graphics card later for one with 
higher performance if desired because I'm not  limited by PCIe 3.  I 
wanted a build that had a jump in performance, and would last me for years.

There were driver (and UEFI) issues at first, but I don't have any 
issues now, and I'm quite happy with it.  For what it's worth, this was 
also my first AMD machine.
