GamersNexus: "Following its Polaris GPU architecture announcement and ensuing Polaris demo at CES, AMD today announced a reduction in price for its R9 Nano video card. The card, which launched in September 2015, is now carrying a Suggested Etail Price (SEP) of $500, a significant drop from its $650 launch price (the same as the Fury X)."
And that is a major drop of $150. That might be because of its unpopularity.
