Right now the old MB is using ddr 400 and has PCI, (one) PCIE, and SATA. Its not a bad mb for what its doing with stock settings, but the bios has no oc options of any kind.
Im thinking a new mb should at least have ddr2, SATA, and PCIE as the main features, but also should be able to oc well.
I'm almost considering upgrading my new mb with something that can handle ddr3, and use the p5n32-e as the P4 mb.
