not to be the partypooper here but... is it really at all useful to cpu mine dogecoins at this point? The difficulty is high enough that you will barely make much even with 1 pretty decent GPU doing many times the hashes/sec your CPUs are
Everyone has a different definition of "worth it"
I CPUmine for 40 Doges a day, Is it worth it?
If Doges go to $10, 40 X 10 = 400, $400 a day is worth it.
If you need to sell your Doges @ 0.00021973 to pay for electricity,
well, no, it's not worth it, I suppose.
BTW: I mine BTC @30gh and think that is worth it also,
again, I see this as investment in my future, not a paying job today.
