due to the recent sky rocket for the bitcoin exchange rate at 1bit:$147 (4 days ago) i have started a small production on my entry level gaming pc. i have had it running for a while now and am reaching up to 31.890 MH/s is this good? its only one graphics card but i was thinking of up scaling to a separate rig. i would be running a minimum of 3 graphics cards and it would cost me £2.45 a day that's for power alone. i was wondering if anyone else on here has a rig?
