Schnuff: Its a useless card, only for Nvidia to show that they could do it...poorly.
I read that because of heat and power problems its running with only 8 TFLOPS and that would show the each GPU is at 694 MHZ....with 2 PCI Express slots and 375 W no wonder.
Anyway for that price you could get 3 GTX Titan Black and change.
The main problem is that devs these days generally don't optimize their games well, or in some cases at all. So even with that card you could still probably see frame-rate drops on some games which have nothing to do with the hardware, but are just the result of shoddy code in the game.
We can improve the hardware quite easily, improving human beings is bit more difficult.
