Intel has tuned the P35 memory controller to support both DDR2 and DDR3 memory, allowing motherboard makers to ship products that can support either DDR2 or DDR3. Both G33 and P35 chipsets use the PCI Express 1.0 standard for graphics and I/O. If you want an Intel-based PCI Express 2.0 solution, that will need to wait for the high-end X38 product.
