i need help
is it possible for me to gpu mine with my nvidia geforce 7100 card??
{very bad idea; you're going to lose money}
I disagree with this, I bought a 5870 and started mining with it on March 1st, I've already made up half of the cost of the card. Difficulty is going down soon so it's a pretty clear path to a free HD5870 for me
Are you taking off the cost of electricity?
at that rate, unless his electricity is really expensive, it shouldn't be that relevant. an 5870 draws about 190W, so at 24x7 operation for those 19 days, that comes to about $9 worth of electricity at the rate i would pay if i paid for my electricity directly.
