Is it really worth mining with a graphic card anymore?
you are getting 1,200 Mh/s but you are talking about 550W just for the video card + computer makes ~700w
at $.10 Killowatt hour you are spending $47 a month on electricity.

You would be better off buying Erupters and using a Raspberry pi & a blue/red furry or 4 Erupters.
The Pi cost $45
Erupters (Crazy price now but I got mine for $10-15)

so in 2 month of electricity you could have a pi running 4 Erupters (depending on price) and get the same performance and spend 15w $1.01 a month on electricity.

Gee, I knew somebody would respond like this...
If you read careful, you will see I don't mine bitcoins, so yes, it is profitable. Also, as I said, it is irrelevant to the question I ask.
