Decided to post this here because this seems like a better deal than most "used" GPUs in this section. Newegg also accepts BITCOIN !
For USA:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202218&cm_re=sapphire_r9_290-_-14-202-218-_-Product$204.99 with free shipping
For Canada:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16814202218&cm_re=r9_290_sapphire-_-14-202-218-_-Product$229.99 with 8.99 shipping
Occasionally these might go down another $20-30 from time to time. Last week the price was $229.99 from $249.99. So keep checking the prices.I know the 480 is due out soon but nobody knows what the speed will be, price , availability, etc. With newegg you can even send it back within 30 days for a refund (no restocking fees if you join their premier program)
These are refurburished but you get 90 day warranty which is alot better than buying a used GPU with no warranty at all.
You will need a special Stilt bios for this GPU.
This GPU hashes at exactly 29.6MH/s and will NOT slow down due to DAG file increases.
Efficiency is average. Have 2 running in one rig using Corsair 750 Bronze PSU using 550Watt at the wall so probably each GPU is ~200 Watts.
A lot of us at the Ethereum Mining forum bought tons of these already and are pretty happy. From time to time you might get a bad GPU but you can always send it back for an exchange.
Only annoyance with this card is the noise. Its loud being a reference design. However since its built by AMD its built rock solid. Very rarely do reference GPUs fail and its even more rare for a reference fan to fail.
