Bitcoins, but the pool I'm in mines other coins and then converts them to bitcoins, (check out the first post where I linked to the pool for more details) giving more coins overall. With the first pool I was in (slush's pool) I got 0.00004119 BTC for 24 hours of mining. With the new pool I'm in, I've mined roughly 21 hours so far and I'm expected to get: 0.00235442 BTC because you mine other coins, that automatically get converted to bitcoins. So for what my graphics card is giving me per day, I could get roughly the same from 2 of the usb devices with a lot less power used. As it goes now I'm not going to be able to mine from this card for to long anyway because this PC will have to last me a good long while. This is another reason I was looking into another method of mining.
