AMD PR refused to have their new Radeon R9 Fury Nano graphic card reviewed by the most respecteful web reviewers around, like Scott Wasson (The TechReport), W1zzard (TechPowerUp!), and Brent Justice (HardOCP), and from what I understood probably because they need only glowing reviews.
I found rather informative the Kyle Bennett's (HardOCP) coverage of that affair.
With reference to me, I'll boycott AMD for at least a year for such a bold move: I think that arrogance won't save AMD from their financial and technology issues.
