I also read a lot about the rate of return being less than the cost of electricity, if I think about it my annual power bill might be $1,000 and I leave my PC on 24/7.
Granted my GPU would be idle most of the time. Assuming my GPU consumed 100W when busy, that would equate to 867kWh per year. At .20c per kWh, that's an extra $175 annually in electricity costs.
So to break even, you would want to mine enough to cover that plus enough to recoup the cost of any hardware purchased.
I'm curious to hear from anyone who's actually tried this using consumer grade equipment. Ie. Recent PC with decent CPU, ~8Gb RAM, Single discreet GPU, purchased for under $1,500.
Did you make any $$$?
I myself have an older Core 2 Duo @2.8GHz, 4Gb RAM, original GPU fried, so I put in a GTX 750. Once I've set myself up, I'll report back here
