Just a little note on my own. I stumbled across this thread looking for dual-socket AM3 boards. A few years back I ran dual AMD 4800+ chips which blew away then current intel junkers.
I was holding out hope that AMD would move along DC boards for the current AM3 chips as well. I already have one PIIx4 and would gladly shell out for two PIIx6 chips if I had a board to put them in.
I think the idea is generally UNDERRATED in regard to performance. With a single PIIx4 and adequate ram (16gb) I can watch a high-res CBHD film at 1600p, encode some films in Ultra Video Converter, Rip a DVD with AnyDVD and burn a disc all at the same time.
I rather enjoy multitasking IN THE BACKGROUND. Something even the top-end overpriced over-valued over-rated intel chips were never good at.
With AMD, I've grown accustom to BACKGROUND multitasking. Why not twice the fun? And twice the productivity. 12 REAL cores/threads for less than $1200. Crossfire, and 64Gb ram?
As for large cases and power supplies? What true poweruser has a mini-tower? Full towers are the norm in high-end gaming and performance rigs. And they generally are in the 200-500 range; same as Aluminium mid- cases. And if you're thinking of Crossfire, or, [strike]gasp[/strike], SLI; you should have a 1000w+ supply anyway.

Asus, Gigabyte, X-Game, and many others have both been releasing multi-video compatible dual socket gaming boards from the time of the K6 and K62; my first experience with advanced computing, overclocking, and timing settings. Is there a need? No, but a real desire.

See my note above. It's not about using 12 cores on one program. It's about being productive with more programs at one time. Think using 4 cores for a game your playing, dedicate three more to a video editor, and another to a background virus scanner. Toss in an internet download and some, LEGAL, bittorrent activity on a dual-threaded downloader.... See the point here...!

One at a time...
First, most current iterations of video software is multithreaded, as are ALL DX11 games.
You're also looking at the WRONG thing from the poweruser's pov. We, ([strike]dare I include myself in this group?[/strike]) are not interested in JUST doing things faster; rather doing more things in less time.
Are 12 cores useful playing Portal 2? Probably not. But when doing, say, 10 tasks at once? Believe it.
Expensive? Dual chip AMD PIIx4/x6 setups will still be astronomically lower in cost than a single I7 setup, all other things being equal. Ram is so inexpensive these days.... Even low end computers such as Dell come with 6gigs and the average HP comes with 7. If you're building your own computer from scratch, chances are you're using 8 gigs, if not 12, 16, or even 32.
You also miss the point that, assuming things being done historically, with the 890FX-DC(xxx) chipset and PIIX4/PIIx6-x64 chips, you're looking at DDR3 memory, not EC/C or DCVM.
AMD's 890gx/fx/ix chipset supports 70 PCIe threads on on 38 available of 42 lanes. Pared with the generally mandatory 850sb chip, SATA 3 (aka SATA 6gbs) is built in. NOT SAS.
You're comparing Oranges to Grapes. Dualsocket performance MBs are not server boards. We're not dropping Opterons here, we're talking about PII chips. And a dual socket board for Phenom chips would, MUST, be designed differently than an Opteron board.
All said; HAS anyone actually FOUND a dual socket AM3 board rated for 85w-125w/socket?
