Yeh sounds great to me too, but I think much like the 2700k which replaced the 2600k, only a small premium should be added on top. 2700k launch price was only $14 more than 2600k, and I would expect a similar % for this new card too.
Looking foward to how well they oc, I'm guessing a good 50-100mhz average higher than current 7970.
