What makes a motherboard good?
Generally, the quality of the motherboard’s power delivery system (otherwise known as the VRM) is the most important form factor. However, the quality of the PCB itself, the cooling of the VRM, form factor, number of input/output ports, and other features present on the board do matter as well. A good-quality motherboard separates itself from the rest only if it passes the test of time, which can happen if no corners were cut during the manufacturing process.
