How do I tell if I have a Crossfire Compatible motherboard? If it doesn't mention anything about it, am I to assume it won't work? I'm thinking of getting another X1950 Pro. If It isn't compatible can anyone point me to an Intel motherboard that is for a lower price? Intel Core 2 CPU 6600 @ 2.40GHz (2 CPUs) 2046MB RAM Radeon X1950 Pro 256MB
