Yeah, I've seen one locally for as low as $170, but whats strange is 680s are going for more. I was looking for a 680/770 to put in a Mac Pro, and the used prices for NV cards are kinda weird. Everything costs more than it seems it should. Just bought a 280x on eBay for $150 shipped. I guess its because the 960 is slower and is at $200-240, and 970 is around $330-350, so the high ender last gen cards still have a place.
I was even hoping with the 4GB memory issue used 970s would hit the market at a good price, but if any are available they are basically at retail prices.
