Do all those GPUS pay for themselves without having a hyped coin like MaxCoin to mine?
not as fast as AMD cards but yes, they pay 2x-3x the electricity costs in Germany.
Which ones? I wanna try a GT 640 4GB out...high N factor might be big soon-ish (it already kinda is, with the upcoming scrypt asics).
I'm mining ultracoin at 415kh/s, you think MRC is a better choice?
