Yeah I'm more interested in their electrical efficiency, MH/W.
I can see the dollar value and also realize they are nice mid level gaming cards, so my thought was I might mine them until the ASIC pyramid scheme hits and then build and sell some budget gaming PC's.
Thanks.
the only GPU thing better MH/W is 5770. These are best in that regards. Lots of old threads where we crunched a shit ton of numbers on them. Sorry, but 5830's are far from the most efficient in terms of MH/W I think the most efficient card for MH/$ -AND- MH/W is the 6870. Per card, my 6870s are 2.55 MH/watt For one of my rigs with 4x 6870 is over 2.2 MH/watt My 5770 is a nice entry level card, and it is more efficient than a 5830, but it is nowhere near as efficient as my 6870. You've never mined on a 5830 @0.95V, have you? It's a beautiful thing. Also, 2.2MHs/watt isn't anything to write home about, at this point. Lastly, don't forget about the 77xx cards. Both the 7750 and the 7770 are around 3MHs/W, and can be bought around the $100 range. I have, but it certainly wasn't more than 2.55 MH/watt per card. And not all would run undervolted stable at decent speeds. So how many rigs with 4 5830s do you have running undervolted to .95? What's the MH/w of each of those rigs? It doesn't work for me to look at what one special gpu can do, I needed 40+ gpus for my farm. Why would the 77xx cards even enter into this conversation? I'm talking about cards that have been available for almost 2 years. Also, the 7750/7770, in terms of density, are no good for a multi-gpu rig(like the 5770). I'm not trying to prove which card is the best for mining.I'm just correcting your incorrect statement that 5830 and 5770 are best for MH/w. For large scale miners the 5830 has always been a power hog. They only perceived advantage was MH/$, but the 6870s could be had for $145 shipped when people were paying $130 for 5830s. |

I'm assuming this is just standard bitpay verbiage:
"Once you press Send in your bitcoin wallet, this transaction is not reversible.
Bit-Pay.com cannot be responsible for any dispute you might have with the merchant."

That, and it's rewarding people who have been hoarding their coins, who are not exactly the people who have been supporting the currency as a method of payment (treating it more like a speculative investment). I like the idea of supporting Bit-pay, but otherwise this BTC only payment stipulation is awkward and arguably unfair.
Bitcoiners complaining about having to buy something with BTC is almost as absurd as saying people who have BTC to spend aren't supporting the currency. Exactly ... the users that are most likely to have at least enough bitcoins on hand to buy one SC will be the miners that have been mining for years and are the backbone of bitcoin. Miners that do it for fun or strictly for profit won't have enough readily on hand or will be cashing them out as fast as they can to fiat currency. I think this its a smart move for BFL to give the existing miners this advantage as they are the ones that will be most affected by the resulting jump in difficulty. I have money tied up in BFL singles orders and would appreciate a small advantage, but if I don't get one, I'm not going to cry about it. I was ready to order last night. I'm really not worried about the process being "fair." Any adult knows that "fair" ended when we stopped playing with toys in the sandbox. I do think it would be healthy for bitcoin for BFL to limit the number of units per order. Yes there will be users that get around the limit, but at least make them work for the extra units. Someone that can order ten at the click of a button will at least be limited to 3 to 5 units using multiple "aliases." With all that said a tried and true bitcoin user will know how to turn fiat currency into bitcoins in under an hour. |

I'm thankful I just moved all everything out of mt gox.
So far I love campbx, the lower exchange rate is worth the piece of mind.

The problem with the lottery method is that buyers who paid later could get there order filled prior to someone who had their money tied up for months. I don't see any need to process orders differently then they have been. It needs to be first come first served.
Good point. But then again, what if (hypothetically) the first ten people order 1000 Jalapenos? There should be an order limit per person. That would be healthier for bitcoin than a lottery system. |

We've been working with Bit-Pay for a BTC exclusive order form. This is meant to both promote the good services of Bit-Pay and give dedicated miners a bit of an advantage in getting in position. We'll have that posted later tonight. Alternate payment methods of Dwolla and BankWire will come shortly thereafter.
Please help... We're respectful of the significance of order position, but we can't think of any good way to organize it other than opening it up to orders and letting it go as it may.
Another alternative is to go odd / even. Odd being consecutive down the priority list and even being a random selection from orders that month.
Any thoughts on this?
No plans for PP or CC? PP will come later. We don't process CC's. Will the bit-pay order form be able to accommodate the trade credit for users that have pending orders? Will we be able to just pay the difference in bitcoin? |

I'm at 525w @ the wall for all of my 4x6870 rigs, and that's with the 100% cpu bug.

Yikes, 6870 uses so much power! Otherwise I would be interested.
You're dead wrong ... in the reference design format, they're the hidden gem of the mining GPUs for both MH/$ and MH/w and availability/reliability. No card beats them, even the 7000 series in terms of both MH/$ and MH/w and availability. They could be snatched up for the same price as the power hungry 5830s. I was buying batches of 8 cards weekly @ $135 shipped in q1 2011. Rigs with 4x 6870s set up properly get 2.3 MH/w and are easy to keep cool. I haven't touched my Win7 rigs for over 6 months. 6870s are still you're best bang for the buck hands down. Good luck finding a 5850 without the fans that die after a month(BTDT). |

I run a really old version of guiminer (newer versions are less efficient) and all 10 of my 4gpu rigs are doing fine with opencl on deepbit.
It must be an issue with newer versions (within the past few months or so)
