Ignore the prior comment.
Yes they do crossfire, because the 7970 is able to support direct X 11.2.
It needs an up dated Ati driver to do so.
The Tahiti supports CGN, But programmers have not started using it in games yet.
Crysis 3 crossfires fine.
The limiting factor is the generation. or more of the case what each card is capable of in DX. features also. Hardware side.
But it will depend on how well each game is coded and made in some cases.
Some games see a small percent of frame rate improvement at higher resolutions, and other can see up to 35, 40 %

No the bridge is created through the Pci-e now.
That`s why 280x dont have to be CF with a cable.
Extra hardware or control was added. You just need and up to date Ati driver to enable it with a 7970 and a 280x. a 280x is a 7970 in a sense. CGN added.
And an update to the audio side, via Hdmi.

Ok so it is clear that both cards can be crossfired based on same core. But in the picture, they have created the CF using bridge whereas you've mentioned it to be based on PCIe whereas they did not mention it. I wanted to read more on this PCIe based CF
