Wow... That was in Dec 2013...
He easily could have sold it for twice the amount
well i wouldn't say he could have
easily sold it for twice that...but if he waited long enough for the right buyer he might have fetched double the asking price. the same goes for all the used 7970 being listed at $350-400, and even more so for the 7950's being listed at $300-350. just b/c there is a cryptocoin mining craze out there right now doesn't mean digital currency mining dictates the currect price of AMD video cards. miners make up maybe a hundredth of a percent of all video card buyers out there...heck, even on a computer hardware site like this, where digital currency miners are sure to congregate and form a far above average concentration of miners, they still comprise a stark minority of video card owners here on the boards. gamers, HTPC'ers, and to some extent video encoders, still far outnumber miners both around the world and on computer hardware sites like this.
thus its hilarious to see the pricing we see today on those cards, b/c if only 1 in 100 potential buyers is actually a miner, then the chances of selling a card at miner's prices is slim to none. i guarantee you that just about everyone listing their 7970s and 7950s for such outrageous prices aren't fetching nearly what they're asking unless they find a miner or a sucker...and that takes time.
if one wants to sell his/her 7990s/7970s/7950s quickly and easily, they'll have to either adjust their selling prices accordingly, or accept what would appear to be a lowball offer relative to his/her outrageous asking price. hell, it may have been before the Litecoin GPU mining craze blew up, but i didn't pay a dime over $230 shipped for any of my 5 7970s ...and now people are listing their 7950s for over $300, LMAO...good luck w/ that sale.
