Asus P5KPL-AM SE iG31 Socket 775 onboard Graphics.. | Ebuyer.com
You don't say what sort of graphics card you've got or even if you've got one already. This motherboard is ASUS (Decent make), supports that CPU and more, uses DDR2 and although it's got integrated graphics, it's also got a PCI express x16 slot.
The PCI-Express slot is PCI-E v.1.1 though, but your PCI-E Graphics card will be backwards compatible and will work. The trouble is, there's very few chipsets out there that will support both DDR2 and PCI-E v.2, especially for the intel C2D line of CPU's.
Hope that helps.
