lol limit 10 per customer. hmmm

I'm an ex-miner. I still love bitcoins, but I've decided it's too expensive to mine for me. Lowered the difficulty a bit for the rest of you Wink

I'm not sure if this is a really good value though.  You can get similar hashing performance (and better gaming performance) from a 6950 for $3 more and you can buy those all day long.  I think the 5870 still edges it out for power draw though.

Going off this.
If you add up the costs for a server (bare minimum)
cpu-                                        $30
ram-                                       $10
psu-                                      $150
mobo-                                  $140 (if you know cheeper then this with 4 pci express then let me know)
hd-                                         $15
PCIe x16 Extender Cable       $12*4
+4*240=$1,353

(4*440)/1353=1.3008 megahash per server cost

going with 6950 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814150523)
+(4*223)=1,253

(going with 420 because it seems reasonable from the mining hardware comparison not sure what a normal megahash is for the card.)
(4*420)/1253 =1.3407 megahash per server cost

according to this site (https://spreadsheets.google.com/spreadsheet/ccc?key=0AsSwOT3E1XTGdGtpa1BQcmJLN2x6TG1MRmxzb29BeFE&hl=en_US&authkey=COWC8toK#gid=0)
power consumption is basically the same as well a little in favor of the 6950.

At bare minimum the 6950 is better then the 5870 at those prices.

Let me know what the average megahash for a 6950 is because that will change the ratio a lot.

edit: found a better costing card for the 6950
