Okay I finally selected a motherboard.  I've settled on the Asus Rampage 2 Extreme.  Below is the complete system of parts I ordered this morning:

CPU:  Intel Core i7 975
Motherboard: Asus Rampage 2 Extreme
RAM:  12 gigs Corsair ddr3 triple channel 1600 ram
Hard drives: 2 Western Digital Caviar Black 1Terra Byte Drives
Power Supply: Enermax Galaxy EVO 1250 watt
Case:  Cooler Master RC-932-KKn1-GP HAF 932 (Black)
Mouse: Logiteck trackman optical wheel contour
Operating System: Windows 7 64 bit

I'm going to give my existing monitor a try on this system to see if it is good enough before buying another.  I still have to order the video card but that is from a different online order place.  Before I do get a new video card, thinking of Nvidia Quadro 4800, I want to see just how well might this system run with an old card like a GeForce 8800GT or ATI HD2900.
