I just realized the prices are high because amazon and ebay aren't allowing regular people to list these items.  I want to sell a 1070 but amazon requires written letter from the brand authorizing you as a reseller and ebay only allows established sellers to sell for over 500. 

This essentially weeds out all of the people who just want to sell their items and eliminates compeition leaving the price gougers free to charge 899 for 1070s.
