I'm a poor student who bought 50BTC some time ago, I don't want to sell yet and im just looking for a way to make more.

So I might as well give up? Because I'm not buying a new card for this.

So I've set up a worker on my PC using GUIMiner and using Slush's pool(http://mining.bitcoin.cz). The program says I'm getting 26 Mhash/sec(Nvidia 8800 GT). Which would make me 0.05 BTC/24h(0.88$), minus the 3% commissions. My increase in electric bill would be higher then what I make.


Am I missing something here?
