Hey, I just read this, http://www.engadget.com/2010/05/10/asus-crosshair-iv-extreme-mainboard-supports-mix-and-match-gpu-s/ with its' lucid hydra tech to support multi gpu scaling across multiple manufacturers, and yet, I can only find the Formula edition... Are they the same thing? I want the lucid hydra tech for my gpu's, and also, if i were to run the 5850 and 5770 with hydra, what would happen? would the 5850 clock to 5770 speeds, and would it basically be like xfiring 5770's or would the performance boost be greater?
