Does anybody "play the lottery" still with 1 or 2 GPUs? I keep one going just for the lols.
I've got an HD7770 tucked away in a host that is also running a database server. No point shutting it down since the marginal cost of the electricity is $0.
I run scrypts in each pc or server i must work on. Must be thousands out there mining right now. even trow some old miners in them sometimes.
