In response to my offer for one of his 5870's:
No... That's too low. Mayyyyyybe 270.
For $270 I could get (2) Sapphire 5830 Extreme's from NewEgg (yes, they're in stock) for $129.99 each!
(2) 5830's = 600 MH/s.
(1) used 5870 = 400 MH/s.
You got tons of use out of them, why do you think you can gouge on the way out? You're a few weeks' too late for that.
If you think we're going to pay June 5th prices for this hardware with the current difficulty and Bitcoin price, you've got another thing coming.
I offered $170 for your card, which is a fair price consider it's used. And what good is it? It's primary resale value is for mining. But what value is it for a miner?
Even at the "low, low price" of $170, it would take 68 DAYS to pay for itself, assuming difficulty stops rising (which it hasn't, and won't).
(As an aside -- difficulty continues to increase. It is not even holding steady, much less going down. The last 2 days the network hashrate was lower, but it picked right back up now that a couple DDoS'd pools are back online)
68 days is a huge risk for a miner. A lot can happen in 2 1/3 months!
