It's probably more motherboard than you'll use with the locked-multiplier i5-2400. But it is a fine board. Yes, it supports AMD's Crossfire (dual cards), but not Nvidia's SLI (dual cards). The 2nd PCIe x16 slot (video card slot) is only x4 lanes rather than the full 16 lanes. But that should not be much of a performance loss unless you are using high end gfx cards. You can check out the specs and features here.
