"This is a gaming card marketed to extreme gamers."
"And since games are probably the most resource-intensive fucking thing, you should expect your GAMING CARD to kick major ass at everything else if it has the capability."
Did you not understand what he said?! It's a GAMING CARD - it's designed to kick ass when rendering games. Everything else is secondary - it's not a general purpose card, and it's not marketed as anything other than a high end gaming card. If it happens to kick ass as a more general purpose GPU, then that's just a bonus - it has nothing to do with its gaming performance. Nvidia sell other cards that excel in general purpose GPU work. I really don't think they care less whether this card, or any of their gaming cards, perform better at cracking encyption keys than something from ATi. Nor do the vast majority of people who buy it.
Personally I'm getting a pair of 680's instead, as it seems a better buy for slightly better performance, but this card does exactly what it's designed to do: be the fastest graphics accelerator for the gaming market.
