No necessarily fanbois, but just gamers with money that buy boutique computers already. They may not really be hardware geeks, but just might be thrilled to buy the most expensive single GFX card available - along with a water cooled 8 core Haswell-E and 64GB of DDR4 RAM (even though they'll probably never use more that 12GB).
These are buyers in a different club than most of us - and their friends have that same mentality as well. Heck, I don't care. If NV makes a profit on it, good for them. We can still make more sensible choices. Some people shop for a suit at Sears, others go to boutique shops where the cheapest suits start at $1200. So what if the number of guys buying suits @ >$1200, if that little shop is profitable - good for them.
I don't know why some people are going crazy over the price of this GFX card - buy something else if it's out of your price range (and as a tech geek, you know you can buy more perf for your dollar elsewhere).
The price isn't the issue; it's that there's nothing to justify the price whatsoever. You keep mentioning performance per dollar, but really, that doesn't even get to be an issue since it's not the fastest card you can buy. If it were $3000 and the fastest card on the market, you'd have something resembling a point. However, it's slower than the 295X2, it's a lot slower than 2 Titan Blacks, and it uses 3 slots. Literally, the only reason to buy this is because you think to yourself, "I want to spend $3000 on a card." Notice how this gets way more flack than the Titan and Titan Black did. You know why? Because with those, you could at least say that you bought them to have the fastest single GPU card on the market. The Titan Z has no claim to fame beyond being the most expensive consumer card ever. If that's the only notable thing about it, how do you expect the price to just be ignored?
