Intel motherboards usually tend to be more expensive then other top brand motherboards and I'm not sure that is a justifiable increase in the price...
There are few manufacturer's out there like Asus, Abit, Gigabyte, MSI, that make very good boards that use either Intel or VIA chipsets for the Intel processors and work really well..
These boards are generally cheaper and present no significant problems..
I've used a DFI(dual MB) on NT for a long time, and then recently switched over to a Gigabyte dual MB and run W2K without any problems.
As soon as the Dual AMD chipset is release, I intend to pick up a dual Asus MB..Regards
