SWEET!!! Actually have had my S2 hashing overnight and whenever we do finally get this upgrade or upgrade kit rather I'll be getting one. I'm sure most with S2's will be getting the upgrade?
It was always going to be a physical upgrade.. between the newer chip and the new chain method it created a window where an upgrade made sense . On the down side if they are still working to squeeze efficiency out of the latest chip it makes me wonder when a new chip will hit the market
the reason I say that is if a newer chip was around the corner, this evolution to the S2 may not make sense .
