On amazon and newegg, the 290x has terrible ratings. I know the non-reference coolers fixed throttling problems. But people seem to be complaining about black screen, freeze-ups and DOAs. Is that really true? How can so many people have those problems? Don't companies test their cards before selling them? So is it that most 290x give problems or is it that the people who have good cards don't review them. Please enlighten me.
