Why are some mobos only for SLI and others only for Crossfire?

hmm ok. yea it was confusing me because I was messing around with an Alienware customization and it had an i7 intel cpu and 2x 1gig radeon cards.
 
rolli is right
Before i7 CPUs,intel chipsets(like X48,P45,X38 etc) supported only CF,but now almost all P55(with the exception of few) support both SLI/CF and all X58 boards support both.(If you need more info,check the SLI/CF FAQ topic in my sig, you can find a section about motherboards compatibilities with SLI/CF)
