I can’t believe that anyone that knows anything about mining would spend 1600 on a card. Only complete noobs would do that. At today’s price and difficulty the roi is 12 months for 850. So you would be buying a used card that might or might not qualify for warranty(manufactures are already making warranties void if they suspect other then factory oc) That is pretty risky in my books. Good for you if you can offload them onto someone that does not do return on investment calculations. And 1600?? That would be perhaps 2 years to make the money back. Nvidia will drop the 2000 series in a few months. 40% faster. And msrp for top line will be about 900. Most sane people will wait. But again good luck finding a buyer.
