Card throttles at above 70 degrees. Mines would drop clocks to 900 ish after some gaming. Need more noise to keep fans effective. Under water my card runs 1100+ constant with fans on very low.
I'm not really arguing but the point is still, despite how much you pay for the Titan, it's still the fastest single gpu in the world. And then again, as A couple of guys have said, if you use it for DP compute, there is no competition from 780.
Titan is priced this high because it has to be. It's an entry level compute card on one hand and a gaming superstar on the other. The GTX 780 is a gaming superstar alone. Ironically, the 7970 is also a compute superstar but now a lesser gaming card in comparison.
And one last time, like I've said months before, if you have the money and you want the product, buy it - it's why we have a free market.
Is it too expensive? (GTX Titan) - yes. Can I afford it - yes. Was i sick of crossfire glitches - yes. Did I want single gpu performance as high as possible? - yes - Buy Titan.
Now of course, you'd buy GTX 780. Titan as a gaming product is now irrelevant. GTX 780 is the obvious choice.
