Yeah this is bullsh*t. While I do understand the need for them to protect their brand, this just imposes wayy too much power to Nvidia. Sure, for now its going to be "you can't give this too much voltage in fear that it will explode." But what keeps them from saying:
"Wow, Asus, that is a great card and falls within all limits - however it is TOO good, too fast compared to future cards, too quiet compared to competition. We can't let you make it."
I mean, damn. They could make EVERYONE use blower style cards because it "doesn't fall within specs" if they wanted. This is a bad move, Nvidia. Very disappointing.
