I need to find a Mobo with 16x16 CFX capability w/DDR2

X38 and X48 are 2 Intel chipsets that support 2x16 in Crossfire.
There are several AMD chipsets, the 580 and 790 both will support PCIe 16x2 but you did not specify for sure if you are looking at AMD or Intel based motherboards.
There are actually a lot of boards out there that will do what you are looking for..........
