A little birdie tipped me off with some new information on a NVIDIA nForce4-based dual Opteron board from Abit that is due to be released in February.  The board specifications are pretty impressive, and include SLI support as well as 4 SATA II ports and dual Gigabit ethernet connections.  Even more interesting is the fact that I am told that this board does not require registered memory and will work with standard non-ECC and non-registered memory modules, saving considerable costs on system.  And with the prices of 200 series Opteron processors dropping to nearly $200, a dual CPU system could be reasonably priced!

Below I have exclusive images as well as the full motherboard specifications listed.
