Yup, it's an amazing card but an absolute joke for the price.
For multi-monitor gaming, it's just 36% faster than a 1050mhz 7970 and that's with the Titan overclocked to 1Ghz. Otherwise, it's only 25% faster!

Performance incresae is a fail for a 230% price increase (Newegg has 1100mhz 7970 for $430 by Gigabyte)
Here is a nice thread on triple monitor gaming of GTX600 vs. HD7000: http://forums.overclockers.co.uk/showthread.php?t=18455827
The Titan only makes sense if you get 2-3 of them. Otherwise, a $500 Asus Matrix Platinum @ 1300mhz would not be far behind honestly.
I think $500 20nm GPUs next year will match the Titan since going from HD6970 to 7970 and from 580 to 680 gave 35%-45% more performance with a node shrink. Titan sounds like an e-peen swinging card aimed at benchmarkers or people with very high incomes or if you need its double precision/compute performance for light workstation use. Would have been a lot more attractive at $699.

Only 31% more performance from a $1000 551mm2 chip overclocked. I am saving my money for 20nm for sure :)
