Anyway, I used strongcoin to open an account and did some freebie stuff now my balance is showing as 5.0e-05 (not quite sure what that means, never mind!). So I decided to mine and installed 50Miner and my hahrate is 82mh/s - not great but it's not a fantastic graphics card.

Does the 5 before the . indicate 5 bitcoins though, do you know?
