It doesn't matter that not everyone is having issues. If SOME are having issues, it makes "good driver and software support" a lot less, believable. And you apparently didn't read the article well because they also clearly said that this is not limited to Navi, neither the problems, nor the poll, nor the driver issues were limited to Navi, but primarily many of the core issues, especially the black screens etc., are. Seriously, we just had one member who updated his drivers and ALL FOUR of his working AMD cards instantly began having problems. FOUR. Just from a driver update. Two days ago.
Last year we noticed that batches of RX 580 cards were dying off right after some driver updates. So yeah, the fact that not everybody is affected does not forgive the fact that there is a problem.
AMD themselves SAY there IS a problem, and that they are working on it. So how do you refute what they've said themselves? Not everybody had coil whine or was bothered by the GTX 970 3.5GB memory issues either, but they are/were STILL problems, regardless. Nobody would have said "The GTX 970 has terrific memory support" in light of the issues surrounding the architecture despite the fact that for most people it was a non-issue.
