Crossfire motherboard. Wouldn't surprise me if it supports PCI-e 2, and I wouldn't get DDR3 anytime soon, its really expensive and doesn't offer much of a performance increase over DDR2.guitto said:Does AMD's chipset that supports the quad core also support PCI-e 2.0? I know it supports DDR3, but Ive seen some Mobos with 4 PCI - E x 16 slots, what is this?
