A motherboard is one of the most important components to purchase when building a new PC as it's the foundation for all of your machine's parts to interact, but it's far from a one-size-fits-all solution in 2025. There are four motherboard sizes available, each with different strengths and weaknesses, with smaller and larger fiberglass rectangles used for different purposes.
As such, there's no easy answer for what the best motherboard can be, so it's vitally important to know the four commercially available sizes, rough pricings, and the sockets available for some of the best processors on the market. After all, compatibility is vital in 2025, particularly if you're eyeing up some of the best DDR5 RAM, best graphics cards, and other PCIe 5.0 components for the build.
