Twice that. I bought them for $200 just 6 weeks ago. Now? $250. the Vega's at $399 are a better deal now."Past performance is no guarantee of future results."
Today, you could sell ATI RX470 or RX480 for at least 60%-120% of last years sale price.
You could mine XMR using the video cards for 1 year, sell the card for profit ( if brought the card at fire sale price)
or break-even price.
In earlier 2017, I paid low $100 for RX 470 or RX 480 cards. I could sell the a RX480 card for $130 at an instance.
