just sent back a Powercolor Radeon RX Vega 64 Red Devil that was having intermittent issues not showing display on boot. kind of like it didn't initialize sometimes it was weird because when it was up and running it was fine. finally got frustrated and contacted the RMA dept and started a ticket. sent it out on the 15th of Jan, and by the end of the day on the 27th. I had a nice brand new looking vega 64 that works no less, in my hands. the emailed when they received it telling me they were going to test it and a few days later I got an email with a tracking number saying that it was on the way, NICE!!! got it and it's good to go, I read so many horror stories from all GPU makers, that I wasn't sure how my experience would go. I have to say it was nice to get good warranty service like that. I know stuff goes wrong, nice to know they'd cover it.
