I'm very distraught about not finding out about this folding til now. I have been mining ltc on dual 7950s for a couple years, until a couple days ago when one of them died on me. I was digging around looking for alternatives today and ran across this and am kicking myself cause this would have been saving grace, but I ran my card into the dirt with normal mining. Now I am here, very fashionably late [like always]
