It's really a YMMV situation. I'm a gamer, so dropping $220 on my 6950 was no big deal, and the fact that I can use it to more than pay for the electricity that my whole system is using makes for a nice bonus.
It's not that unusual to find overpriced used merchandise of any sort... people always think their crap is worth its weight in gold. Craigslist and ebay are the best places to find items like that.
Ok... then why did he still have the card?

Am I reading this right? Is that a way to add an pcie slot?

It's specifically for adding a single upgrade slot to an HP thin client computer. So likely it's not what you're looking for.
The "minimum requirements" for a 6950 is a 500Watt power supply... they pull about 169 Watts @ load with stock settings. I'm running an XFX 6950 @ stock and netting 318Mh/s with a Corsair 600 Watt PS with zero problems. I wouldn't be scared to add a second card if it had the extra PCI-E connectors.
I question that 8% variance though... the 6970 has more shaders and a higher clock speed... you might be comparing the 6950's with unlocked shaders. Those cards are getting a little harder to find.... my XFX has a locked bios and I may not be able to unlock those extra shaders (people have been having a 50/50 chance on this particular board revision).
If you do have unlockable 6950's though, you basically already have 6970's.

For the 6990 @ $722, based on current rates ($14.5 @ Mt Gox) for a 6 month time period:
Revenue per day: 7.29 USD
... less power costs: 5.76 USD
Revenue per time frame: 1330.60 USD
... less power costs: 1051.18 USD
Hardware break even: 125 days, 10 hours
Net profit first time frame: 329.18 USD

Re: Asus M3N72-D not recognizing Sapphire 6790 in either slot
Do you have the latest Mobo BIOS?
Might want to just RMA the card... maybe you can get an advanced ship option that allows you to get the replacement up front.

I wasn't able to drop my 4850 any lower than 620MHz memory, and currently I'm running with a core of 735, and netting about 82MH/s... but that's using RivaTuner in Windows. I'm going to mess with the MSI Afterburner build later tonight... but I need more cooling I think.
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.

Thanks for the clarification!
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.

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.
Not sure if this is a good buy at $270 after MIR...
If it was for gaming, I'd say no, unlocking the bios wouldn't get you much by way of performance gains. For bitcoin mining, it's a much better value. Those extra shaders can make a nice bonus for only $30 more, instead of paying $100 more for a 6970. Plus, if you're overclocking, that bios switch could be a godsend.
The key to the prices was finding the card in stock at a reputable vendor. That is why I used TigerDirect and Newegg for my price/availability checks. Doing some extra searching, I did find a 1GB 5870 from a vendor with some positive ratings that claims to have the card in stock for $419.99. Everyone else lists it as a special order or out of stock item. Considering it's a discontinued item, good luck getting any "Special orders."
Of course, you could always take your chances and buy a used one for only $249 from bobbyh!

Second hand cards are very hit and miss... people who know about bitcoins are asking a lot more than they're worth and as a result everyone else is asking for more. I did however hook a buddy of mine up on a used 5830 for $115 through Amazon.
Fair enough... how about this revised comparison?
*** Image moved to first post ***
- I've taken the averages of the lowest two scores to use as the "Stock" performance numbers. This can account for some variance between cards that come tweaked from the manufacturer as well as different settings/mining apps.
- I've taken the averages of the highest two scores to use as the "Tweaked" performance numbers, to be used as theoretical gains.
- I didn't touch the wattage figures for now... there's too large an amount of unrecorded figures. I might do a search for some stock wattages later.

Well I was averaging the scores, and people conveniently refrained from posting their wattage consumption... >.<
The 6990 is generally for those unconcerned with price/power consumption. Even with an adjusted power consumption though, it's still a relatively good performance/power card (@ 450 watts, it would score a 1.69 MHash/j). There's also the matter of availability, or lack thereof.

***EDIT*** Revised chart to include "Stock" vs "Tweaked" results and show the possible gains to be had.

Notes:
- The MHash performance and wattages are an average of the values from the Wiki site. There were a few cards that I pulled wattage information from other sources due to not being listed on the Wiki. So don't be too surprised if your card does not perform as well as these averages at stock speeds.
- I did not list cards that were no longer/not currently available with two exceptions: the 5830 and the 6990. Nobody has the 5830 available for a "reasonable price," and nobody has the 6990 available. I didn't include eBay for these availability considerations (although you can get used 5830's there for about what I listed it for), or the large number of Google/Pricewatch shopping vendors that I consider to have questionable reputability. YMMV.
- I pulled the majority of prices from Newegg and Tiger Direct. I did not include prices for tax, shipping, or rebates.
- The 5770 still has the best overall performance for a combination of power consumption and price. Newegg has a 5770 for $89.99 after rebate, making it an even better deal. Get 'em while they're still available... the rebate is only good till 6/30, and unlike most rebates, it's good for two cards per household. The 6870 makes a solid second place choice, but I'd probably recommend spending extra on the 6950 if you're going multi GPU and looking to maximize your performance vs space. Of course the 6970's and 5870's are still kicking around for the brute-force-money-is-no-object fellows... ^_^

- With these revisions, the 6950 is painted in an even more favorable light when you factor in the possibility of unlocking dormant shaders and overclocking. The 6970 also rises to the occasion with great performance vs power consumption if you don't mind the higher entry cost. Older cards like the 5830/5870 offer great performance/watt but are unfortunately held back by pricing and availability of these discontinued parts. Buying second hand is a mixed bag, as people generally want more than the cards are worth (eg, people asking for $200+ for 5830's).
Thoughts?

Keep in mind that the guiminer software is still in development, so it may not be unusual to see some odd behavior. Myself, I noticed that the MH/s between my CPU and GPU tabs were reversed at one point... my CPU was hitting 50MH/s while the GPU was reading 14MH/s.
