https://bitcointalk.org/index.php?topic=10541.0 <-- topic on same graphics card as you
unless you got plenty of ASIC miners running into 100's GHashs, there is no real point mining bitcoin solo anymore. Pool is the best way to get anything now for most.
With that Graphics card though, even on a pool, you will not reap much rewards. In all honesty, i would say with your current hardware, probably start mining an Altcoins

Primecoin, Litecoin and Goldcoins are some relativly easy alternatives.. you can then use an exchange to trade these for Bitcoins
