I've been running ufasoft on my work laptop for 6.5M/s over the last few days and I've mined a few hundred shares with it. Depending on which pool (eg deepbit with pay per share), you are guaranteed at least some pay. The way I see it is that any pay is better than no pay.
I think as a moderator of this board you should better inform the new posters, rather than just slamming them down with a simple answer.
You might get a few hundred shares, but I doubt that's anything near 0.05btc. And as far as getting them with a cpu goes, the difficulty is now going to go up in around ~9 hours. Then it will be twice as hard to make bitcoins.
