It has been alleged that the XFX Double Dissipation AMD 390 graphics card based on the potential Fiji pro architecture has been pictured out in the wild.  Although rumours from Chinese news sites regardling leaks can be somewhat un-reliable at the best of times, from my personal point of view, this looks like the real deal.  Of course anything should be taken with a pinch of salt but looking at the alleged specifications, there is every chance that this is the actual XFX 390 Double Dissipation graphics card in the flesh.
The leaked specifciations are touting a maximum 300w TDP which looks about right given the 1 x 6pin and 1 x 8pin required to power this particular model.  Without speculating too much as I am personally not a huge fan of rumours unless they look to have something with substantiating, the current rumour mill specifications put it against the GTX Titan X in terms of power so it will be interesting to see how it compares to the upcoming NVIDIA GTX 980Ti card.
