AMD: yes.

Sapphire: Meh. They earned a good reputation maybe a decade or two ago, but other brands have been making equally good or even better cards more recently. (Also, my last Sapphire card's fans, including their replacements, were continually developing weird noises and eventually failing.)

I'm happier with PowerColor these days. Currently using a Hellhound RX 7800 XT with great results.
