What is the importance of the motherboard?? in Processors, Motherboards and Memory Posted yesterday at 05:52 PM Most of the time it's if you want to overclock a particular CPU. The more durable the components, the higher quality it is, and you're more likely to overclock your CPU more efficiently, as well as having the motherboard working for years, and maybe even a decade or two. Sometimes you may want a certain amount of PCIE slots, or it having a M.2 slot. Maybe you want better onboard sound, or onboard wi-fi. I typically don't look for these types of "extras", but most people do.
