I think the AMD Fiji cards are going to be special, and Nvidia knows it. Here's a snippet from the conclusion of the Tom's Hardware Geforce GTX980 ti review.
"So why not dust off our highest-of-the-high Editors Choice award? Call it the Fiji factor. AMDs HBM-equipped answer to GM200, or at least what were expecting to contend with Nvidias flagship GPU, is purportedly imminent. Without knowing how itll affect the enthusiast graphics space,
were reluctant to declare a victor, as much as like the GeForce GTX 980 Ti. Though that might sound unfair to the star of todays show, rest assured, a winner will be declared soon."
I'm pretty sure they have Fiji on hand under NDA, along with most other hardware sites. We're getting close to blast off!
