I'm putting together a PC for a friend who just received a free X1900 XT, and he wants to make it a pretty good computer around that card, mostly for video editing. I'm going with a dual-core processor because of that, and he also wants it to be compatible with Crossfire. So, which Core 2 Duo motherboards are best for Crossfire (which support it at all?)? How about AMD? Actually, which would be the better processor for him, a Core 2 Duo or an Athlon X2?
