I'm mining at about 570/600 Mh/s. At the current difficulty, I should expect an average of about 1 BTC per day. I have been mining for well over 12 hours on the Slush pool and only earned about 0.03 BTC (confirmed) and 0.16 BTC (unconfirmed). Even assuming an optimistic 0.20 BTC for 12 hours, it's still way less than half what I should be getting in theory (and on average).
A friend of mine who has the same hardware as mine, as been running it for days and he averages 0.3 BTC with 600 Mh/s from Slush.
Is this normal and expected?

better question is why do they take such high commission
They take lots of legal and financial risks by running such a large exchange. I say they deserve every bitpenny they get. But yes, competition is good. |

Not a good idea, you'll make 144$ in a week. The week after that difficulty will rise and dismantle your prognosis.
Possibly, or perhaps the bitcoin price will rise accordingly as it has done in the past. Either way, I think it's still an interesting, albeit grossly approximate, way of thinking about Mhash/s. |

This is very approximate, but I thought you'd be interested in knowing that at the moment your hash rate is roughly equivalent to the amount of money you'd be making with the current difficulty and exchange rate.
For example, if you have 600Mhashes/s, your revenue would be roughly $600.
This is a useful tip when you are trying to do some quick calculations in your head.

There are three serious problems with this approach:
1. CPU mining leads to very little earnings, even when you have thousands of visitors.
2. It may piss off users far more than ads. "Why is my computer so slow when I visit your site?".
3. Google will label/ban sites using this as malicious/malware.

Just spend on hour searching for available bitcoin related domain names.. It's incredible how many have been taken so far....
Jesus H. Christ, even bitcoinbonanza.com has been taken.  |

CPU mining is just not worth it, particularly if you are paying for a VPS. And GPU services on the cloud cost a lot (hundreds per day).

Based on amazon.ca prices, it looks like my best bet is 2 HD 5830. Thoughts on this?

I would also go for a 5870, you can pick them up cheap sometimes and they are very good for mining. In Canada they seem to cost more than a 6970. Does the case have a standard ATX power supply? And is there an extra case fan (or at least place for it)? There is an extra fan already. I'm not 100% sure that the existing PSU is ATX. I would buy a new PSU though, assuming it fits in the mid-tower of the Lenovo M57. |

Yes, but you'd be wasting money with a 6970. You're better off just getting a reference 6950 and flashing/unlocking it to a 6970.
Are you sure this is still the case? The 6950 is only 800MhZ while the 6970 is 880MhZ. Overclocking both, I assume the 6970 will go farther. Right? |

I own a Lenovo M57 which I could use as a dedicated mining rig. Could I just replace the 280W PSU with a Corsair Builder Series CMPSU-600CXV2 600W ATX PSU, and add an XFX Radeon HD 6970 2GB GDDR5 PCI-E video card? Or are there problems with these components and my machine, compatibility-wise? Thank you for your help.  |

Have you tried using Diablo Miner? On my MacBook Pro, it detected both built-in cards and provided statistics for both. It may work for you on GNU/Linux as well.
