915P is the standard LGA 775, DDR2 and PCI Express chipset from Intel. It has been designed for mainstream and high-end desktop computers and thus requires a discrete graphics card (PCI Express only). As the performance advantage of 925X over 915P is marginal, 915P should be the chipset to go for most users. Also it is the chipset most LGA 775 motherboard will be using.
