I've just returned my 3rd card to Newegg, not sure I want to try a 4th.
I purchased a Sapphire Nitro 5700XT a while back. and upon initial boot my screen would black out and on during BIOS setup... after I managed to get through that it seemed to be okay in Windows but I did have issues running games and only got worse. RMA'ed the first card, installed a second and same thing, screen fading in and out in BIOS, sent it back right away... third one, nothing but Black screen in BIOS... I change from Display port to HDMI and it seemed to work, (for a couple weeks) until it just totally died, it's back in the mail now.
Using a RX 480 everything runs Pretty good, but I've been having a few issues.
This is in a new build witch ran fine for a few months with a Sapphire Nitro RX480.
I'm having a hard time believing Sapphire is building bad cards, but I'm not sure where to look.
Current system consists of:
ASUS ROG Crosshair VIII Hero (main board (803 bios))
AMD Ryzen 5 3600 (65W CPU)
Crucial Ballistic BLS16G4D30AESB (DDR(16GB@3000 X 2))
Seasonic 650W Titanuiim PSU (fried 1050W Platinum)
