Reviews and Problems with Sapphire HD7970 OC 3GB GDDR5
Showing 1-2 of 2
miss and miss for me, but I think it was just poor luck.
13 August 2012
Summary: Giving a 3-star rating as I'm fairly certain I just have/had REALLY bad luck. 1st card would gray- or vertical lines-screen at random, usually at idle, but sometimes under load, regardless of drivers, clocks settings, BIOS switch positions, even in another computer. I contacted Amazon for a replacement, and they cross-shipped me one STRAIGHT AWAY. However, the second one not only had the exact same issues, but it's cap/choke whine was 10x worse than the 1st card.
Summary: This card worked great out of the box. But slowly started giving me more and more problems. Started black screening while playing Battlefield but that eventually turned into black screening during all games. I also had a coil whine but it did not bother me that much because I play games with headphones on but can see how it would irritate some. Luckily amazon is awesome and is letting me return the card.
