"The MSI P6N Diamond is an Intel socket 775 motherboard that supports Core 2 Duo/Quad/Extreme and processors running on a 533/800/1066/1333 MHz Front Side Bus. That covers all Intel CPUs back to the Pentium D. Chipsets are the heart of the P6N Diamond, and this board is based on to very solid performers; the nVIDIA nForce 680i northbridge and nForce 590i southbridge. That puts a pile of PCI Express lanes at your feet, allowing dual SLI videocards to run in x16/x16 or quad PCI Express x16 videocards to run in x8/x8/x8/x8 mode."
