This site have  Ashes of The Singularity so its what it matters for most here, if you or other know other site that bench the new cards on this game pls say im interesting to see.

That site its just another site like any other, just watch about 10 diferent sites and you get the idea if worth buy or not.

I never trust in only 1 but if at least 7 say the same thing then i can trust.

Ty for share, there is 4/5 that i didnt saw yet.

For what i see where the 1080 really leaves behind all the rest its on 4k, since its the only that its unlocked to 60fps. ( Awsome) 

I suggest you wait for the AMD to reveal their cards, if you are not in the hurry. The prices of cards like R9 390 will go down even more and boy, those are some powerful beasts. About the 1070/80, hard to tell at this point. You will definitely get an increased performance, but most of the "benchmarks" you see now were done under the controlled environment.
