When upgrading a PC to a faster processor, what should you ensure about the motherboard before ordering?

When upgrading a PC to a faster processor, ensuring that the motherboard matches the current form factor is crucial for a successful installation. The form factor determines the physical size and layout of the motherboard, which affects compatibility with the case and other components. Motherboards come in various form factors such as ATX, Micro-ATX, and Mini-ITX, each with specific dimensions and mounting hole placements. If the motherboard does not match the form factor of the case, it may not fit properly, leading to installation issues.

While compatibility with RAM type, support for the graphics card, and considerations for power supply are important factors in a build, they are secondary to ensuring that the motherboard fits in the case physically. If the motherboard does not fit, no other considerations will matter because the system cannot be assembled. Therefore, confirming form factor compatibility is a fundamental step before upgrading any component, including the processor.
