Just setup my first mining machine and getting about 320M/hs which is pretty good (at least I think) for the rig it's in.
If you want to mine, mine Litecoin or other altcoins with that. You will lose less money that way (unless you have free power).
If you want to make money the most profitable thing you can do with your rig right now is sell it and buy
BTC with the proceeds (if you believe
BTC will appreciate in value).
Sorry to tell you but the easy mining days are over.
I have a USB Block Erupter from ASICMINER. It PWNs your mining rig at 350Mh/s and uses way less power (only 2.5 watt). You can get them at around $60 which is probably less than you bought your graphic card for (even then it won't make you money, I just mine for the fun).
