I currently have 16 R9 290x cards sitting in their boxes waiting for my two rigs so I can set them up. Hopefully they come soon because I am tired of waiting.
Jesus man!
What are you doing? Have you calculated how much money you have lost waiting on the rigs? You should have set them up with milk crates in the meantime as a temporary solution.
12MH/s+ just laying around waiting while you wait on a couple of cases?! You are crazy or lazy or both.
