is Asus GTX780 DirectCU II faster than a reference R290?

[TTRock]

I know R290 is faster than a 780 . but Asus GTX 780 DirectCU II is overclocked . is this faster than a reference AMD R290?

I m going to choose between , R290, Sapphire Tri-X R290 or Asus GTX 780 DirectCU II. Which one would you choose?

I'm leaning over to Sapphire Tri-x 290 . But i just can't trust AMD drivers and hardware quality.
