FYI, you should start seeing benches of the Geforce Titan in linux later this coming week (if Micheal fixes the login on openbenchmarking).
I read the benchmarks today, the card is somewhere between 680 and 690. Which is excellent.
But its price is completely off the scale even for such performance. Which is bad.
That means, its a "good" card
Does your Titan support GOP? I mean when you enable Ultra Fast Boot. I read somewhere that it would work with MSI, EVGA provides firmware updates and ASUS cards currently have got no GOP support.
