Well, I just took a gander at eBay, and let me tell you, that's even worse!
As P.T. Barnum said, "There's a sucker born every minute."
I'd like to know what these cards are supposed to do besides Bitcoin mining, because I have several! Apparently I don't realize what all they can do for you.
Because for Bitcoin mining (in about 6 hours, after the difficulty reset) they will make you about 0.257 BTC a day, or $4.01 (when BTC is 15.60) or $3.54 after electricity is taken out.
$200 for a card? $350 for a card? Come on, you gotta be joking me! It's a 5830, not a 5870!
Hmm, I think I should go sell some of my 5830s that I haven't opened yet! Then, get a 6870 with the profits!
