TweakTown posted a review on the Sapphire Radeon HD 7970 GHz Edition Vapor-X 3GB Overclocked Video Card

AMD's Radeon HD 7970 GHz Edition has become quite a funny model with companies not jumping on it quite as quickly as we would've thought they might have done. The slow pickup meant that I felt it was time to do a little investigating to see what exactly was going on with the model. The general thought process was that the lack of chips available meant that companies couldn't get the quantities they want, but it doesn't seem to be the main reason.

It seems that partners aren't all that happy with AMD when it comes to the HD 7970 GHz Edition; especially those that put in a lot of time and effort when it came to making special versions of the normal HD 7970. With companies still having stock and also not wanting to put more time into R&D, some are choosing to not worry about the HD 7970 GHz Edition.

Combine this with the fact that a lot of partners offer both NVIDIA and AMD based cards; those particular ones can just concentrate on the NVIDIA based GTX 680. This makes a whole lot of sense when you consider the two companies who have promoted the new model the most are Sapphire and HIS, both of who are AMD only partners.
