in 10 days 1 BTC will be 25$  But then in 20 days 1 BTC will be 0.25$ BTC is overheating now and we don't need to break 20$. |

I have FSP Aurum in 2x5870 rig and Enermax Modu87+ in 2x6970 rig. Enermax is best - very efficient, quiet, stable but high-priced.

$0.27/kWh -> $210 monthly for my rigs

I have one of my rigs crossfired and I am noticing 0 difference in mining between doing that and running each monitor independently, as one datapoint.
Me too. What is real difference VGAdummy vs. CF? 0! I have 2x5870 a 2x6950. No difference. Bonus of CF is ability to use rig as mighty CF gaming rig. |

We've already seen deepbit take 50% of the total hashing power before.
And now others have more than 50%. You don't know who are others. IMO is better to know several well known pools than one unknown mass of others where can be hidden someone with >50% power. |

Why do you not recomend CF? I have 2x HD5870 in CF and fair performance 2x 380MH/s without dummyplugs. I can mine with each card separately.

Check your GPU temp on the troubled card. I had a similar problem when a GPU went >90C.
It is temperature problem mostly. I have 2x HD5870 and second was steadily 100Mh/s under first. One 120mm fan gives me this 100MH/s, so it is definitely best coin/buck hardware :-) |

Next difficulty level will probably be 400k+
Mining is still too profitable to slowdown growth of network hashrate.

I have a windows desktop/rig with 2x unlocked 6950 Crossfire. 11.5 slows down mining from 720Mh/s to 710Mh/s. But I'm using it for gaming too. So I have reason to stay with 11.5
