WTB GPU (5830?)

[dollartrader]

Currently have a rig running 5830 x4. One of the cards keeps dying. Reboot the miner and all is well. Seems to be random and not temp related.

So, I want to replace it. For the next 5-6 months, I am not concerned about power costs so whatever is the most bang for the buck. I'd even consider upgrading all 4 if I found a deal.

Mining at eclipse 5830 x4 cgminer running about 11160-1180 (until one of the cards die)
