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.
