Its hard to really blame the board partners for not supporting a return, just like retailers they are not the one's who caused the issue. But good CS is good CS, so it will have a baring on the brand of my next GPU.
As for NVidia, it appears that they have realized that the cards are still selling very well and a vast majority of people either don’t know about the issue or don’t care, and never will.
Especially as now it appears some retailers and board partners are picking up the slack in terms of dealing with the people who feel disgruntled. Hopefully the increased scrutiny that should now be put on NVidia products will ensure this doesn’t happen again, and may even result in better products.
Personally I am extremely dissatisfied with NVidia and I’ve gone from someone who’s been almost exclusive to their brand (I even own a Shield tablet and was eyeing up a g-sync monitor) to someone who will almost certainly buy an AMD card next and for the foreseeable future. In reality it will mean nothing to NVidia, but their opinion no longer means much to me either.
