You can say that now, but in a few years, who knows what refresh rates will be normalised? I know right now those very high refresh rates are still niche (which is why I suggested frame limiting), but it does seem that if the card can output a very large number of frames, it should be able to do that without absurd coil whine.
It's just an indication that the card was not designed with that in mind, or that it was not built with components glued to prevent it. When you consider how much these cards cost and the amount of power they use, it would be nice for them to be a quality product from the aspect of preventable coil whine.
