Isnt it a false economy buying hardware these days for mining?
You could always try CPU mining...

I just got mine in the mail. Ordered 3, but only one setup so far. Getting about 310 mhash/s out of it, so seems to be a pretty good deal.
Does running these cards in Crossfire offer any advantage to simply plugging both cards into your motherboard?
No in fact it can cause some issues to mine while crossfired.

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.
Thank you, this was exactly the point I was trying to make.
Also, owing to the versatility of the CrossfireX platform, anyone who gets a 5830 and then later comes across a 5870 at a reasonable price can run both cards in Crossfire. However, I can't say that I'm an expert on this subject. Does running these cards in Crossfire offer any advantage to simply plugging both cards into your motherboard?

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.
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.
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.

Sounds like fraud to me. Keep your business honest people, retailers have to make a living too.
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. http://forum.bitcoin.org/index.php?topic=26576.0
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.
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.
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.
Newegg's got a few 5830's left @ $130 - Great for Mining!
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.

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:
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.
Code:
BFI_INT VECTORS AGGRESSION=8 FASTLOOP=false worksize=128

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

in my local market its still more efficient to get 2nd hand 5870's 
Got one, raising my 900Mh/s to 1.2 Gh/s. These cards are very reliable and fast.
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)
