I had four different sets of 980s and 970s (six cards total) and never heard it. Here I got accused of being either stupid, deaf, or a liar about it. I think the whole thing was overblown. None of the reviewers mentioned it. We just heard about it because of these forums. People love to have something to b!tch about.
Glad you you were lucky to get so many cards with out the issue, a lot of us didn't. Why are you still in this thread? You just like to browse a thread about issues you don't have and say others just "love to have something to b!tch about".
Please post less often.
