Maybe a little but that's the negotiating headroom. I can find them in NL for 330 and in DE for 320, and that is new. I took 60% of newprice as it's over a year old, did conversion to USD and then converted to LTC. That led me to 62.4LTC.
Also 300 eur is incredibly steep as that's basically its price new.
Also i don't care about ebay because thats mainly USA and prices are different there.
bitcoin graphics cards don't age like you think they do, this isn't the car market, 5970s that have been used since bitcoin started can still be resold for close to cost.
I have 2 7950s but I sure as hell wouldn't sell them for less than 300 each when I decide to eventually sell them.
