This is not the same thing as the world being flat. This is pure fact. The VRMs are not PHYSICALLY CAPABLE of outputting the power needed for an overclocked GTX 570.
Nvidia says card probably won't work past 1.1v. Card doesn't work past 1.1v, so the card is bad? Also, yes, the 590 is the same setup, but it's not the same GPU, the 570 is a scaled back version of the chips used in the 580/590. It isn't a worthwhile comparison.
The fact is that SOME
570s have failed at conditions where they shouldn't have. The opinion
is that it's excessively high, and that the card is poorly designed.
With absolutely any card available, you can get a DOA, you can get a timebomb, the 570s are not actually notably ahead of the curb when it comes to either. There are plenty of people that have had their 570s running at 1.1v since December without any
issues. Far more than have had their cards die. Telling people to avoid a card because of a few oddities is foolish. Overclocking a 570 is just like overclocking any other card- you can only push so far before bad things happen, so don't get careless.
