So let's see. $175 x .88 = $154. If you expect to get over that, or anywhere near that price on a forum filled with educated buyers, just get the listing up on eBay now and save yourself the headache. I bought an Asus Matrix 5870 for $130 shipped. The two guys who have posted offers are about the best you'll get.

From what I've read, 220PPI isn't too high (at least for cell phones). IIRC, the Galaxy S3 has 313PPI and the Iphone 4s has 326PPI. But that's on a much smaller screen even compared to the 15.4'' display.
but remember that a pixel on retina is divide another four so it is giving you greater detail The iphone 4s has the retina display.  |

Since no one has one, nobody can say for sure. But odds are a million to one that it works in the exact same way the current hardware from BFL works. You plug it in, turn it on, and it connects to the mining program which then uploads your shares to the pool (or solo mines) of your choice.

Right before I sold mine in favor of 7970's, I was pulling down +/- 1btc a day out of 2. One was on water, massive overclock, the other was on air, not-so-massive overclock. My electricity is 6.9c/kwh, at current prices I was making right around $4.change a day, paying them off in 6 months. If you can get a couple for under 350, maybe some xfx's that have the second lifetime warranty available, I'd say go for it. They are sort of, well, prone to failure so figure that in to your overhead, and it might make more sense to get newer generation cards.
7970 will drop in value fast. Even at 7c electricity I don't see the wisdom in purchasing a 7970 solely for mining (would have to have some gaming on the side). Maybe if the electricity was free. I had seven 5830's that I bought for $110 each..... but also got a steam key for Shogun 2 download... which sold for $10-$15... So, about 95-$100 for each 5830. A year later, I've sold all but one of those... total depreciation? Well, nothing.. 7970 a year from now will be worth much less. 5970 is getting close to a good buy point.... Another couple months should see them under $300, probably around $275. Right now? 5830 (or 5850) is probably still the easiest to get at a price that won't drop much in absolute $... but 5870 might be the best value when you figure in hash rate & efficiency. 5870's are what I've been buying, price point at $160 or less (a little higher for XFX). I think most people just choose to ignore their equipment depreciating in value when figuring profit.. Sorry, but I'm going to have to agree with the crowd on this one. 58xx prices have been artificially inflated by the mining market for over a year now. The technology inside the cards is almost 3 years old now. Granted the cards game pretty decently, you can find a much better card for playing games at the same price range (5870 ~ $150). Which means not even gamers will want the 58xx cards when the miners are done with them. However, 7970's will still be very good cards for gaming, even if at a discount. The point is, the current and previous returns you've made on 58xx cards are completely negligible because gpu mining was still profitable when you sold the cards. I honestly see the last string of 58xx cards selling near the $50 point. Which, since you mentioned percentages, is actually a larger loss than a $350 7970 (and who actually pays $500 for a new 7970 anyway?). |

Just wanted to mention that I finally got around to fixing the 100% cpu bug in my system, and I updated to 2.5.0. I got a nice 7mhash/sec increase on each of my cards at identical settings. Very nice! |

LOLOL, I guess my estimations and math were a bit off when it comes to an 85*F room and dual psu's. My 600watt psu bit the dust today. I'm filling that space with a nice 1kw gold rated unit though. |

+1 rep! Notice the new addition today.  |

I'm not 100% sure about these numbers but my 4x5870 with 900/150/1,08V was pulling 550W from the wall. This seems really low but I remember that my efficieny was little under 3. (hashspeed/wattage)
In other words: You can run 5x5870 from a single 1000W PSU if you lower the voltage on every card.
Very nice. I'll try settings close to those. |

a 5970 @ 715 0.95v and 765 1v pulls 213 watts on an 80plus gold PSU and does 683 mhash/sec and 3.2 mhash/joule The computer idles at 170W without the 5970 installed (it has 4 other vid cards but they were idling too). With the 5970 installed but still idling, computer takes 233W (5970 takes 63W at idle) With the 5970 installed and under load, computer takes 363W (5970 takes 213W under load) I also have reference 5870 in the same system and reference 5850 in a different system, but will take time to get numbers figured out since it requires miner downtime. 5850 0.96 v 835/150 for just over 80 watts. 330 Mhash
Just so you know, setting at 0.96v isn't actually 0.96v. Volterra programmable voltage regulator operates in steps below the max voltage step. According to my XFX reference 5850 BIOS, the steps are 0.95, 1v, 1.0375, and 1.0875. Your 5850 is actually operating at 1v, not 0.96v. Thank you very much for the info. You really don't need to figure it out if it means you're miners go down. I greatly appreciate you finding it though. |

I've found that most of my OpenCL related issues go away when I use SDK 2.5. It's been much more stable for me. And then I use 11.12 because I run CGminer. I need to be on 11.12 because 11.6 doesn't support headless gpu's, and 11.7-11.11 have the 100% cpu usage bug.

So with some reviews that I've read which go over power consumption, along with the information here, I've basically found that the 5830 uses ~ 125 watts, 5850 uses ~ 150 watts and the 5870 uses ~ 200 watts.

Thank you two. I appreciate that info. Keep it coming! |

A few problems. Number one, those online calculators don't allow for 5 cards. Number two, I don't know how much the cards are actually pulling when I look at the calculator. I can factor in my cpu and ram and other parts, but I want to know how many watts each card pulls from the power supply so that I can be the one who does the math and figures out which power supplies I will use. For instance, I want to run my power supplies at less than 80% load because it's continuous. If that calculator says a 650 watt is fine, I don't know how many watts the system actually draws, so it may be running at 90% of the power supply capacity.

Thanks. We've had a large influx of scammers lately who all have "great feedback," but never post links or give names. I was just getting it squared away.

I'm looking for some power consumption numbers so I can correctly choose the power supply to run my rigs with. I'd like some accurate information on the following: 5870 power consumption while mining @ 900/300 1.1v 5850 power consumption while mining @ 900/300 1.1v 5830 power consumption while mining @ 900/300 1.1v Thanks in advance to anyone who helps me out. |

So where are your refs and feedback?

If you buy at the right price, gpu mining will still pay itself off and then some before ASIC hits. And then you'll have the resale (or re-purposing) of the cards.
