sapphire pulse rx 5700 owner here, no matter what i tried the black screen issue remains for me, it's so annoying, how you are working oj something important and boom black screen which requires restart, and the rtx series is just slightly expensive where i come from. at first i thought let's wait few months it'll be fine but using this since December the BLACK SCREEN issues remains. if i sell the card i would get only 50% of the value.
i never used Nvidia card before, been using amd cards for about 6 years now, never had issue like this before with amd, amd disappointed many fans.
