MSI X48 Platinum Intel X48 Express Motherboard
The three main advancements with the Intel X48 Express chipset over the Intel X38 are support for DDR3 - 1600 memory and Intel Extreme Memory Profiles (think EPP/SLI memory for DDR3), the PCI Express 2.0 standard, and 45nm 1600MHz Front Side Bus multi-core processors. Most everything else about the Intel X48 Express chipset is identical to the Intel X38 which preceded it.
