The motherboard plays an essential role in the following aspects of your computer system:
Organization of devices: Everything is eventually connected to the motherboard. The way that
the motherboard is designed and laid out dictates how the entire computer is going to be
Control of the devices: Built-in to the motherboard is the chipset and BIOS program, which
between them control the majority of data flow throughout the different computer systems.
System Communication: Almost all communication between the PC and its peripherals, other
PCs, and you, the user, goes through the motherboard.
Processor Support: The motherboard socket depicts which choice of processor you can use in
Peripheral Support: The motherboards components determine what type of peripherals you
can use in your PC. For example, you can not use AGP cards if you only have PCI slots.
System Performance: The motherboard is a major factor in your system's performance; it
dictates which type of processors, memory, system buses, and hard disk interface speed your
system can have via its connectors or BIOS settings. Often if you are upgrading after a number
of years you will need to replace the board, CPU, and memory.
Upgradeability: As motherboards are developed newer processors may not be compatible with
