Depending on how you OC it, these cards have been known to break 300Mh/s

There have been better cards then this sit and be patient. There's a reason its been in stock for several days.

Of course there are better cards than these, but the fact is that you simply cannot buy 1120 Stream Processing Units for under $200 anymore. I'd love to get a 6950 dual-bios card that I could flash the extra shaders out of, but they're becoming scarce. I posted this for the benefit of any miner who sees the usefulness of getting this card at this price, whether its a beginner's first GPU or an expert's ticket to sweet Crossfire delight.

According to Mining Hardware Comparison, aside from the 5830, the only other GPUs to break 325Mh/s are the 5850, 5870, 5970, 6870, 6950, 6970, and the 6990.

Yea I'll agree the deals are few and far between I just don't want newbie miners to think that the 5830 is the best card at any price. It's solid but only because it was at 110. Just to show deals are still out there here's a post from less then a week ago:

This for example would crush a $130 5830 if you were building a dedicated rig.

It's close, but taking their average Mhash/s rates from MHC at each sale price, the 5870's 393.46Mh/s divided by $189.99 = 2.07Mh/$

The 5830's 286.45Mh/s divided by $129.99 = 2.20Mh/$

They are virtually identical in terms of performance per dollar, with the 5830 having a slight advantage.

I got 6 of the 5830s on their way as we speak should be good for 1400-2000Mh/s (seen some of the sapphires do 250mh/s and others do 300+mh/s)

[Opsamk]

Got one, raising my 900Mh/s to 1.2 Gh/s. These cards are very reliable and fast.

[somebadger]

in my local market its still more efficient to get 2nd hand 5870's

 Dont these make about 0.18 BTC (@ 300 mhz) per 24 hours now - at just todays difficulty level? (without factoring electricity)
 Isnt it a false economy buying hardware these days for mining?
 Would be grateful of some ROI calculations

Each card will pay for half itself(at $0.20/kwh) within 30 days. If the bitcoin market fails within that 30 days, you can get a refund and still keep your $60 profit.

If you kept reading the thread I compared this to the 5830 at $110.

I'm getting around 440MH/s out of mine.  I can't remember where I saw it, but there was a chart comparing MH/s, cost, and power consumption and the 5870 is THE card to get for MH/s vs. Power used.

If you add up the costs for a server (bare minimum)
cpu-                                        $30
ram-                                       $10
psu-                                      $150
mobo-                                  $140 (if you know cheeper then this with 4 pci express then let me know)
hd-                                         $15
PCIe x16 Extender Cable       $12*4
5870   $190x4
=      $1,153
(440x4)/1153=1.53 megahash per dollar(full server cost)

with 5830
5830   $110x4
=        $833
(330x4)/833=1.58

So as long as you go the absolute cheapest route 5830 rig at 110 is better but not much so. If you add a case or more to the cost at all the 5870 at 190 will probably overcome the 5830.

As you can see when you add the costs of the full server it is almost as good as a 5830 at $110. If I switch the cost for the 5830 to $130 this is the calculation.

(330*4)/913=1.44

If we use your numbers in staid of mine its this.
(286.45*4)/913=1.25
(393.46*4)/1153=1.36

Also keep in mind thats the bare minimum server so if you put more money in the gap will get larger. You are just thinking to narrowly and not thinking about the full picture.

Is this a static difficulty calculation?

With a 6990 I was getting ~ 1.2 BTC per day ~ a month ago, and that has gradually reduced to 0.3*-0.4* BTC per day now

[lpcustom]

I bought four of these 5830s last month for $109 each from Newegg. They are decent miners. The average hashrate I get out of them is 265. That's using:

Code:

BFI_INT VECTORS AGGRESSION=8 FASTLOOP=false worksize=128

One of them failed on me and I replaced it with a 6950. The rest have been going strong for over a month with around a 50mhz overclock.

Sounds like fraud to me. Keep your business honest people, retailers have to make a living too.

It's not that I was thinking too narrowly. I was simply comparing two video cards at their current prices, all other things equal. The 5830 is among the best cards available right now in terms of performance per dollar. Although it may have been the case in the past, as it stands today there is no 5870 card available for $190. That's the reason I pointed this deal out - it is available right now.

I don't really support that method, but they did jack up the price. Also, "customer satisfaction" wasn't met since it turned out to be a card that did not meet his needs within in the allowed timeframe, so it's quite returnable under common considerations.

[kidage]

Its weird that this isn't sold out yet, something isn't right.

[lowlevel]

Its weird that this isn't sold out yet, something isn't right.

I don't think it's weird.  I've seen about 100 used ones available to buy from miners since the last difficulty increase. One more increase, and we might see many more cards and mining rigs available.

[gdubya]

I got a 5830 as a second card to play around with and run at 1x. Sure wouldn't be dropping 250+ on a card to do that with. 

[Bitcoin_Silver_Supply]

There have been better cards then this sit and be patient. There's a reason its been in stock for several days.

5870s are extremely difficult to come across and 5830s are quite literally the best option at the moment amongst available cards. That said, they are jacking the price since cluing in to their demand and I doubt there are many more left on Newegg or elsewhere.

If you're looking for an immediate low-cost miner and your second hand market isn't great the 5830 is about the best you can get today.
