My thoughts on this is, Nvidia wanted nothing more than the TITLE. They wanted to say they have the fastest single GPU card in the world. That's why its priced like this, that's also why it wont sell. Its a pretty good card but around the net I am seeing people say oh titan? nah let me get a second 680.
Anyways AMD is making a dual GPU card that has dual 1Ghz chips on it. Sounds really epic TBH.
