You are thinking of a 7970.....the 7870 aint got shit on a 680.
On Topic
If you look at what ArchViz can be done in UE3 and CryEngine 3 in real time at ~60fps from people who arent the best at optimization im not shocked this studio managed to pull this off on one GTX680.
Also, from my bad google translation it seems alot of the lighting is actually prebaked and not interactive at all, not a bad thing for scenery and vast scapes and all....but what happens in tighter situations and when err if there are dynamic lights. If the AO is precalculated then would any sort of spell that brings light out make objects seem ill lit?
Honestly beyond the Baked lighting, the Hair shader and their implementation of SSS im not blown away by this at all. And Baked light doesnt even impress me anymore.....we are beyond this arent we?
I imagine next gen consoles will be able to pull this off with a little more optimization and some sacrifices to the high res assets.......just get better Maps god damn it.
Not even the Particle effects impress me that much.
This could have been done on a PC from last year.......beyond the baked GI in the background which is absolutely amazing nothing kills me.

I said the same thing before, about not being blown away by a majority of the tech demos, and was promptly lambasted.
Certain things have wowed me, like the particles and lighting in the UE demo, the character models and cloth/hair in this demo, the environs in certain PC games/mods, etc, but not yet a combination of the three. As time goes on and the tools evolve, I'm sure we will see something come together, just like now in Halo 4 and The Last of Us for the current gen in relation to their tech demos
I noticed that the "Thousands of Characters on screen with physics" thing died down after NNN
