Needless to say if ATI can bring this card out a tthe same or even better lower than the NVIDIA 580 series then it has a winner (drivers permitting).
Now i know intel has the faster setup at the moment but you would think at least one review site would throw one of these at a Bulldozer for testing.
Hell give me one i,ll test the crap out of it 
Anandtech are using an overclocked I7 3960x so that makes them pretty much the newest of the review setups that i can see.

compare these two like results for example.

B3 at full with 4x aa and 2560 for both reviews the only difference really is the cpu and the canucks one is overclocked to 4gig.
11 fps difference for the 7970
and about the same for the 580 so that shows very roughly you get 11fps boost with the newer cpu.
now show me an overclocked bulldozer galdangit
