Here is how I see it :
-no other 5870s on sale on eBay or Google under 200 GBP and even above that I could not find only at 300 GBP maybe
-79xx series will be crap for mining right now and at prices of 420 GBP for 700 mhash/s ( ratio is 1.67 )
-BFL Labs may be a scam and even if they are for real then it has 0 resale value and no other uses like gaming or encryption breaking so very risky etc.
-5970s are going on eBay for about 400 GBP and get a maximum of 840 mhash/s so that ratio is 2.1 which is crap as well
Any more suggestions ? What are you going to mine on in the future ? 5xxx cards ?

Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

Worse you aren't going to get 840 MH on a 5970. Not without massively overvolting it and likely cooking the VRM within a year.
More like 750 MH/s.
What is your electrical rate?

Electrical rates don't really matter to me  ( I work for the power company ) And yes, here in the UK-EUSSR we pay around double what you pay for a 5970 in the US. |

If you have free/stolen power then who cares. Any card is a good deal.
All that matters is MH/$. With no electrical cost just about any card if profitable in 6 months.

As I said before I am not "stealing" any power or making others pay for it. I work for a local power company as an electrician. No stolen cables or altered meters etc. I really envy you over in the US getting a 5970 for $300 with warranty and all that etc. I really am unsure how to invest in mining from here on, hence this thread. |

The capital cost for GPU is immaterial to the never ending electrical cost. I ask "What is your electrical rate"? You answer: "Electrical rates don't really matter to me ( I work for the power company )" WTF does that mean? |

Electrical rates are currently 0.00 ( benefits package from the company up to a set amount of consumption eg not really unlimited but good for a mining farm ) |

What kind of total monthly/quarterly consumption do they give if I may ask?

Let's just say that running 10kW 24/7 won't be a problem. But so far I am not really using any of that. Maybe I should start a mining company on GLBSE if I can find the time for it ? |

Then you can kill FPGA from your list. They would be pointless. A 5970 will produce ~$120 per month at current difficulty/price ratio. Even @ $600 per card you are looking at a 5 month payback period. Simply buy as many cards as you can afford (and are willing to risk) that have the lowest $/MH. Done. Given the bad price of 5970s then 7970 are likely you best bet. If it were me in that situation I would buy one to experiment. |

Not many choices right now. |

if you're not paying for electricity essentially then a 5830 would be worth it if you can find them, £60-£80 for around 300Mhash

The problem with these older 5xxx cards is availability. It's like they've gone straight extinct. Wonder if the gamers dumping them for 7xxx or GTX 7xx will solve some of this. |

I wouldn't be surprised if it were so. In my country (Poland) power company workers also get some free electricity (AFAIK they still have to pay but they get it super-cheap). |

5xxx series availability issues? How about going with 6770 cards then? They're very cheap VLIW5 cards, priced at slightly over 2/5 of what a 6950 costs here in my neck of the woods. I've been running a couple of Sapphire 6770/512 MB cards for 7 months with no failures, each of those little beasties overclocked to 995/300 without any overvolting resulting in slightly over 230 MHash/card. Originally, I clocked them at 1000/300 but that would result in a couple HW errors/day (no hangs). 1010/300 was unstable. I couldn't help but laugh and pick the "BFL PROFESSIONAL product" in your survey meaning should BFL ever release a professional product, go for it  As to receiving free power as part of one's benefits, hello you Americans, welcome to Europe  I'm just wondering, what do the benefits of coffin manufactury workers are? I'm betting oblong. |

I'm betting oblong. I always thought the 6xxx series are much worse than the 5xxx series because of less shaders and crappy VLIW4 not VLIW5 like the 5xxx with SDK 2.1 and downclocked memory. |

Sounds like you've answered your own question: the 5970 seem to be the best best for you at the moment.
I don't watch ebay prices much these days, but over the past few months I've seen a number of 5870s going for under $200USD ($160-180).

Bullshit spread by individuals who forget to shut up when they have no idea what they're talking about. A hd6770 (juniper-xt) is basically nothing more than a re-branded 5770 with some minor bios tweaks completely orthogonal to mining. So are 68xx cards (barts). VLIW4 starts with cayman (hd6950). There is a difference in shared count but nothing as drastic as people make it sound. EDIT:: I was asked to post an example At stock clocks: hd 5850: 725 MHz * 1440 SP = 1,044,000 hd 6870: 900 MHz * 1120 SP= 1,008,000 The stock 6870 is about 3,5% weaker. That's not actually a bad choice, especially considering that it can be purchased new with full manufacturer's warranty. Anyone buying a used card risks spending their money on a device having a only a month of life left in the tank. |
