If they are giving you $60 per month why don't you keep them
What would be your offer though?
Note that shipping and escrow costs will be mine
Power Monsters? Undervolt them, my friend, then they draw less then a stock RX card, you can save 70w~. Power here is 0.05$/kWh, i get 290~ h/s, easy math
I can help you with the draw. I sell bios mods but in this case, just google VBE7 bios editor. They are absolute beast at the moment, I would probably consider it for 110$, but i don't think we'll deal, but now you may have learned how to squeeze even more awesomeness out of these babies.
