I love you rigs for the love of god please switch those GPU miners to a scrypt base coin because you will earn more. But I think you know that already given how old the post is...
I don't alt..

Well... unless you are paying free energy for those GPU rigs, you ARE losing Money just from the electricity, but hey I cannot change your mind. I just want to help a person who IS making a wrong mining chose for those GPUs.....
Because from my experience switch all my GPUs to Litecoin I earned MUCH more BTC equivalent than mining straight BTC....
I feel so sorry for those GPUs.... they could have more potential mining Litecoin than straight BTC...
