Free electricity isn't.
Solar farm or wind turbine in your back yard costs more than electricity from net.

In fact that's a terrible waste of energy/resources!  In fact that's a cost of security and P2P currency system. It's daily cost is 66000 USD. Significant part of it goes to electric power industry. Last 20 blocks had 46 transactions per block in average. So 1 transaction costs 10 USD! Yes, it's quite ineffective right now. |

536 USD. I can wait forever.

5830s are the most cost effective, but they are hard to find anymore. The 6870 is the next best, since it is only a little more and can go up to 330 mh/s. Only $160 at Newegg this weekend...
Only in shortterm view. 5830 is worst in Mhash/s/W. It is crippled 5870, so it has power draw of 5870, but only 2/3 output. |

No, you're right. 5970 is best in MHash/s/W. I have straight comparison... 5970 vs. 2x5870 vs. 2x6970 and I definitely prefer 5970. If you can buy it, don't hesitate.
What could be the right price for it?  I bought older one for 250 euro. Where? Was it used? Sure. But with remaining warranty until october 2011. |

I want the best video card for MHash/Watt and 5970 is ok. I have checked again the comparison table and 5970 should be the best solution.
Am i wrong?

Sorry, but for those questions each major pool got his own thread:
It is combined attack targeting more than half of bitcoin network. Not only one pool. |

(Athlon X2 3800+ EE, 1x5970, PSU Enermax Modu82+ 525W, 8GB Flash)
710MH/s => 400W whole rig measured at wall plug

As usual everyone vastly over estimates needed power. Running a 4x5870 rig and a Kill-a-watt monitor I measured my rig to pull about 900Watts from the wall on a gold standard PSU, which means about 785Watts to the system.
So any quality 800 - 850Watt PSU will do you fine, just make sure you get something with either a single rail, or rails that can handle the amperage you draw for the GPUs.
1kW PSU is a good choice for 4x5870 mining rig. 800W pulling from PSU, but for 24/7 duty you need some reserve. Due to capacitor aging you need 20% reserve for 1+year life span with 24/7 utilization. http://extreme.outervision.com/psucalculatorlite.jsp |

Pause mining, before playing a 3D pc game.
It is not necessary. I play some PC 3D games with -f160 on 2x6970 in crossfire. The Witcher (1) for example. Video acc. is other case. |

I think it's a horrible idea, just like the JavaScript miners.
Nice tech demo, but don't ever serve this to my browser or I'll never return.
I have same view. It will be tollerable if any visitor can choose mine or not to mine. Running miner on background without visitors awareness is bad bad idea and I hate that sort of web, never come back and recomend it to all my friends. |

would you share your version pls?
I prefer to not fork Jade's project. I'll do it, only if Jade not. Let's your request be an another vote for minimalistic UI. Jade, can you create more practical version? Small icons and width max. 250px. |

I have a 1200 watt power supply, but want to put 3 5850's on one mother board.
You can power 4x5870 with that 1200W monster. I have 2x5870 powered by 600W PSU, drawing 520W including PSU losses. Another PSU draw unnecessary power. |

you could get it narrower if you use that timeago plugin, just edit the text to make it shorter  Thanks, it's much better.  |

Great job. It is too big so I did a little mod...  |

Nice bash script. Thanks for share.

In 20 days difficulty will be nearing a million.
There is no such thing as "needing" to break a barrier or drop down in price. Supply and demand of bitcoins will dictate a fair price.
The fair price at the moment is around $18 to $19.
Yes, it is possible. But if price goes too high... supply can bump up followed by panic sellout. Final price can be $12 or even $0.1. I'm expecting some correction during this or next diff. level. Fair price at this moment is about $10. $18 is overvalued price by expected increase of difficulty and net hash rate. |
