user10871: I have just started Bitcoin mining and am using GUI Miner. I have an AMD 7870 OC edition that is mining for me. Currently i'm getting 380 mhash/s, is this good? Also how many of the accepted shares are worth 1BTC?

Welcome to mining. It's a blast.

Currently i'm getting 380 mhash/s, is this good? 

For Bitcoin, it's unlikely to be profitable unless your electricity cost is very low. See How much Bitcoin will I mine right now with hardware X? for more information.

Also how many of the accepted shares are worth 1BTC?

None. It is unlikely that you will see 1 BTC total mining on that card during its lifetime. See the above link for why.
