I wonder how long they will last?  Has miner demand finally turned around?

You shouldn't buy these. At 129 it isn't worth it because when you calculate the megahash per dollar you get 2.325. You might as well go for a 5850 in staid of that because its ratio is 2.424.

Is there a particular 5850 you can link to that is in stock with price so we can verify this math?

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system. - GA

I dont know of a place where you can buy them currently but the price on newegg is 165(http://www.newegg.com/Product/Product.aspx?Item=N82E16814161332) it isn't unreasonable to reach 400 megahash on a 5850. 400/165=2.424.
A 5830 can reasonably produce 300 megahash.
300/130=2.307 (looks like in my original calculation I went with 129 and forgot the 99 cents)

That's the math behind those numbers. If you cant wait for good opportunities to arise you will lose money.

edit: the ratio for an amazon 5850 would be 2.482

It's very easy to get 320 out of a 5830 with latest drivers, 1.5 Phoenix and 3% hack.
320/130=2.46

Right now, there are some in stock. I could buy them. But I am not.

Right now, the BTC is $13.50, and there's no (rational) reason to believe it's going up any time soon.

The payoff period for $129.99 + $7.56 shipping is 79 days at the current difficulty, which is about to go up in 1.3 days (sure, not a huge leap, but it WILL shave off some earnings).

So 82 or 83 days to payoff -- sorry, but that's too risky for me.

I know some people are critical of me on here. But I'm putting my money where my mouth is. I don't want to competing with hundreds of other miners to unload 5830's at fire sale prices in a month or two.

You know what scares me the most about Bitcoin?

The fact that every 2016 blocks (about 11 days), 100,800 new BTC are minted. That means that, to maintain the CURRENT price of $13.50, we'd need $1,360,000 of NEW MONEY entering the system every 11 days.  Considering that Bitcoin isn't *that* convenient, popular, or necessary for day-to-day life yet -- and the Mainstream Media seems to have declared war on it -- I see the market correcting even further until it hits an equilibrium -- which unfortunately we be lower.

What does that mean for my rigs? Well, I'll be making less from them. Hopefully something will happen to increase BTC demand -- because that's the ONLY thing that's going to raise BTC prices long-term. BTC can't rise in price from a bunch of speculators buying & selling -- if anything, the price would go down from attrition (as Mt. Gox & Tradehill -- "the house" if you will -- take their cuts)

Just my .02 BTC.

Oh, I forgot to mention --

I looked at eBay -- the COMPLETED LISTINGS -- and it looks like the going rate at eBay is coming down.
Selling for $140 with free shipping -- and you can't ship a 5830 for less than $8.

Let's see...$129.99 plus $7.56 shipping, then I have to ship it to somebody -- I wouldn't be making anything.

So I don't want it for mining (83 day payoff), nor to resell on eBay.

Never thought I'd be passing up a 5830 like this -- I'll admit, it takes some getting used to. My brain is almost hard-wired to snatch up these things. By my reason has to override my emotions -- things are different now.

If you don't operate by reason, you're a fool. And we all know "a fool and his money are soon parted".

Unless BTC shoots up to $18 or $20 in a few days, I made the right decision.

That's assuming that all BTC is being sold. I don't have any solid stats, but I'd assume that a lot of people are hoarding coins rather than cashing them in every 11 days.

But, you still have a point, even thought it might not be as bad as you think.

Believe me, I've been doing a lot of deep thinking about Bitcoin and its fundamentals.

For example, as more and more people mine, the difficulty goes up. What it basically does is slice the pie into smaller and smaller pieces -- the pie stays the same size.

But which situation is more likely to result in a higher % of BTC being sold immediately:

1000 miners getting the BTC produced in a given week

OR

2000 miners


I'd say 2000 miners. It's a smaller piece for each, but statistically you're more likely to get more of them sold, since the smaller miners (newcomers, etc.) gotta pay off that $160 card that bought on eBay Wink  Just kidding -- but you get what I mean.

If the same money went to a smaller group of miners, it would be more likely that a great number of BTC would be hoarded.

Complete BS. Two of these will eat a single 6970 alive in terms of hashing power @ lower price tag. I would get two instead of buying a single 6970. It doesn't apply to everybody though since I have dual PCI-E on my old P5E board.

I'm confused... you bash him for comparing MH/$ ratio of 5830 to 5850, then continue to compare 5830 to other cards over their MH/$ value...  Huh

320/130=2.46



I was just going for simple numbers but the person below is getting 423 megahash with his 5850. 423/161=2.62
Its still a better card and I didn't even get into the lower power consumption or the megahash per total cost of server which does make it a even better card.

I win.

You do realize I never recommended getting a 6970? The only two cards I believe are worth buying are the 5830($109) and the 5850 at the 160 mark. If you can find a card for less then retail and it beats these ratios then by all means get it but at the lowest retail price the 5850 and the 5830 are the best.

What I'm trying to say is this card is better than a 6970 pricewise and performancewise. With that being said, obviously there's no need to compare it with 5850 since 6970 is better than a 5850.

I would love to see an overvolted 5830 compared to this person's 5850. You gotta compare apples to apples.
