If true, then two 670's for 800 is still a better deal and would be faster (minus potential SLI issues). For me, this is way the hell too expensive. Not because it costs $900, but because I always have to buy two cards and I am not paying 2 grand for cards.
For me, Geforce Titan will be a nice benchmark read over a cup of coffee. I can't even feed my two 670's with the games I play let alone two of these ridiculous things. I am an unreasonable hardware buyer, but this is too crazy even for the likes of me. 1.5 years after release, a next gen mid range card will come out and be just as fast and cost $400. That would make me absolutely vomit all over myself after paying 2k for these cards.
