Choosing a motherboard is a critical step in building a computer, as it determines the type of processor, memory, and expansion cards that can be used. In 2009, several factors needed to be considered when selecting a motherboard, including the socket type, chipset, and form factor.
The socket type determines the type of processor that can be used. In 2009, common socket types included LGA 775 for Intel processors and AM2+ for AMD processors. The chipset determines the features and functionality of the motherboard, such as the number of PCI Express slots and SATA ports. Common chipsets in 2009 included the Intel P45 and X58 chipsets and the AMD 790GX and 790FX chipsets.
