Maybe it's just my pc config... I'm very disappointed. They did replace it once, but the one I received was even worse. lol At that time there was a software update and the first card started behaving normally as it should. After the most recent windows update it started to fail again, when booting windows I get a black screen. Downgraded widows version installed latest driver, no go. Connected a new DP cable and it booted at second try... Now I need to do some work while I have the PC up and running!
