wow, thats a sweet rig. sweeeeeeeeeeeeeeeeeeeeeeeeeet rig. Well done. Do you manage to pull out more than it costs in electricity ? I'm guessing yes. is it X11 or x13 that uses like 40 watts a card ?
Thanks.

I used to have about 60 7970s back in the scrypt glory days (late 2012 to mid 2013ish), needless to say that they are all paid off many times over. I've sold off about half of them, and now use the rest (29 gpus) to solo mine ethereum. It's worth it for me since I have cheap (~6c usd) power and already had all the required hardware. They were all sitting in a drawer waiting to be sold until ethereum came around.
I wish they were consuming only 40 watts! Each card is burning 200 watts.
Gotta say I had fun setting up my gpus again. ASIC are so boring! No skills required.
Nice Yeah I have to agree on your last point. I have 2x 5870s that I dont mine with anymore, I doubt they could turn a profit nowadays
