That fluctuates based on difficulty. Currently a single 6990 produces about 0.58 bitcoins per day, or $9 dollars worth of them (at $15.5 exchange rate which also fluctuates).
At the next difficulty of about 1.6m, it will generate 0.50 BTC per day, or about $8 dollars daily.
Price would have to increase by quite a bit, or difficulty would have to stagnate, if you want it fully paid by mining.
It will pay itself off partially in the long run though, even after counting in electricity. Maybe even fully if price appreciates in the near future.

It really depends on your usage model. The 5770 is currently the best (readily) available performer when comparing power consumption and initial costs. If you're looking for the most performance you can cram in the least available space and the up front money isn't a huge concern, go for something like the 6970.
Using the bitcoin profitability calculator and just changing the hashrate, cost, and power use of the video cards (not including the rest of the PC costs/consumption), the 5770 @ stock shows a $1.67USD/day profit with a 66 day "break even" (the card paying for itself). The 6970 shows a $3.44/Day profit with a 99 day "break even." Of course these calculations don't account for the difficulty going up, but it shows that long term, the 6970 is the more profitable card.
Of course, a lot of us little guys can't be dumping $340 here and there, which is where a card like the 5770 shines. We can only hope that video card manufacturers don't notice these values and adjust their profit margins accordingly.

So, a 6990 would be a "no-go" in any case? What is it's profitability/day?
A 6990x2 is two SEPERATE video cards... it denotes someone using two 6990 video cards in Crossfire mode. Just like a 6990x3 denotes someone using 3 6990 cards in Crossfire mode.
So @ $722 per card your total would in fact be $1444, not misleading in any way. Keep in mind that the MH/s are averages based on user input, so YMMV.

I think 5770s are the best value now on their own. To get a true valuation you would have to take into account how many cards per system as well. And add the system cost in that number of cards.
Higher speed cards gain back some of their higher cost with less system cost per same total GH/s.
That is, two systems total 4 x 5770 would be about 800 GH/s.
But with 6990s you can do that in one system. So you save the cost of a second system.

Yeah, I know, it took me some time to find them at a reasonable price in Europe. Found them in pixmania for 120€. I should have them this week.

That table has both 6990 and 6990x2, meaning a system with 2 6990 cards in it.
Yeah, but a 6990x2 card doesn't cost $1440, so I think the mhs/$$$ calculation is misleading.
HD 5850 is missing on the list.
I didn't include it due to lack of availability and reliable pricing. The few vendors that do have it are price gouging... or you can try your luck on ebay.
A 6990 has 2 GPUs.
How come it's only ~820 mhash/s then? According to this table it's at least 1,436 mhash/s - https://en.bitcoin.it/wiki/Mining_hardware_comparison

is the 6990 from the table single core?

A way to look for reference cards is to look for the AMD logo neat the PCI-E connector (the bit that goes into your mobo) I hear.I hope this helps.
Not much chance of doing that online. Call sales dept... ya, can you check if it has a AMD logo next to the... oh what, can't open the package? Because the warehouse is in Kentucky and you're in Bangalore?
HD 5850 is missing on the list.
I found that Sapphire 5770 GPUs have better fans and heatpipes that keep the temperature about 10 C cooler than alternatives.
Thank You.
I'll look for those ones then. Just needed some way to differentiate. You didn't need to select special versions like reference ones or anything? I would just order them online so whatever comes is what I get. I guess that's what most buyers do anyway.

I'm buying the last easy to get stock of Radeon Hd 96950s with reference board as pictured.I hope this is still reference,in UK.The easy to get stock is £178.50 for that gpu from pixmania,so if ny1 still wants what looks like an unlockable card,please go for it b4 they restock with permanently 'locked' cards,if u r looking for a radeon HD 6950 card that is.
Does this look like an unlockable card to u guys?http://www.pixmania.co.uk/uk/uk/8766002/art/pixmania/radeon-hd-6950-2-gb-gddr5.html
Plz advise me on this.
After that stock is gone,you'll have to pay at least £220 or more to get that same card on reference in the pic.

Excellent chart. Thanks for that.
I'd like to pick up a couple 5770.
Do I need to look for reference design or unlockable specs?
Will any mfr. do fine? I've seen Asus, Saphire, HIS, XFX. All good?
Thanks!

5830 "tweaked" at 318 Mhash/s? How, exactly? water cooling + 50% overclock?
I don't understand how people are having problems hitting this with their 5830s. I simply opened the box on mine, set the core/memory clocks in AMD GPU Clock Tool, set fan speed in MSI Afterburner, then started my miner with some parameters found in the HW wiki and it immediately hit 316 MH/s. Did I just get lucky?getting 316 is very good. you got a card that is very stable at such a clock speed.
a more reasonable speed for almost every 5830 would be ~300 mh/s at a clock speed of 980.
so it seems you are pushing yours a tad faster then the majority and if the thing runs without
crashing in a few minutes/hours more power to you.
also your choice of mining software plays a role. phatk is the way to go versus others.
