Thanks for the helpful math and bump, Matthew. Guess you didn't get what you were asking for yours (hence the thread spillover/you looking to troll all 5830 postings), or you are tooooo cheap, and/or are looking for handouts.
Last I also checked, they do any proof-of-work thing, including mining bitcoin, namecoin, buttcoin (among others, all with diff exchange rates), along with, I don't know, graphics rendering.
Two late model, crossfireable, most games-on-absolute-max, graphics cards are always handy, regardless of the current absolute bitcoin mining and exchange rate, and a lot better than someones nVidia-hashing-getting-nothing-or-WoW-on-Low.
Next time, also link where the 5830 sits among the other cards (comparatively pretty high at low price/good btc hashing). Unless someone wants to drop $300-$600 per card, these are a sweet deal (latest was $100 for both).
Topic: WTS (2) Sapphire 5830 (Read 919 times)
These cards make 0.26 BTC per day, assuming a hashrate of 255 MH/s. And the difficulty will go up this Friday or Saturday, so you won't get that.
I'll help you with the math:
.26 BTC/day = today
.195 BTC/day = this Friday (assuming a difficulty increase of 33% -- very likely)
.195 * 14.00 per BTC (pretty generous!)
=$2.73 a day, before expenses
This is a 160W card, which means 3.84 KW per day. At 11 cents per KW/h, that comes out to 42 cents.
= $2.31 per day net profit
So keep that in mind as you bid up this card.

Good afternoon everyone! I picked up 2 of the Sapphire 5830 on the 1st of this month and like many others I'm putting these up for sale. (Difference is, I'll take market :-) ). They were installed in a Antec 900 case (great airflow), kept stock, and always cool. (I mostly do Second Life type stuff, which I need to throw a bigger card at). I've listed them on the bay-of-E at

I started the auction at $100 for the both of them with no reserve. If you are high bidder (and trusted/repped), I might consider a clearcoin-charity-escrow backed btc trade. If you have any other questions, send them my way. Thanks for looking and have a good day!
