im just trying to see which brand is unlocked because i dont want a situation like im in now with my 7970
the sapphire dual-x's are unlocked (core and memory voltage).
I get about 690-720khash out of it for scrypt.
I also get about 680-700 mhash out of it for sha.
even with fans at 100% it is VERY quiet compared to the gigabyte cards.
and it even comes with an HDMI cable.... was a nice surprise
