Quick Shopping Tips:

CPU Overclocking:  The quickest way to improve the system performance is to overclock the CPU. It is a must-have tool for extreme gamers and overclockers. The frames per sec in a game and graphical performance are raised as the CPU frequency is pushed beyond the stock speeds. A highly stable power supply by the VRM is required to overclock CPUs. The higher the cores count, the higher the power is needed, so choose a motherboard with a suitable no. of power stages accordingly.

Memory Overclocking: Even though it’s not as popular as CPU overclocking, memory overclocking directly impacts system performance, but not as high as the CPU. Improving memory clock speed allows performance boost within games, overall speedup of the system, and faster rendering in design applications. It isn’t a must-have feature, but it wouldn’t cost much to have it.

Build Quality: Motherboards with high quality and durable components are less prone to faults and failures. Armored slots prevent them from breaking too often, and the backplate and I/O shields prevent cracking of PCB and breakage of ports. You won’t regret spending slightly extra on a good quality motherboard as it will last a long time and save you from frequent visits to the repair professionals or the pain of replacing a motherboard after it is dead.

Storage: M.2 SSDs are the fastest drives available now, with PCIe 4.0 M.2 the best of them. The motherboard should have a suitable quantity of M.2 and SATA slots to cater to faster and long-term storage demands. Gamers require more M.2 drives for speedy game load times, while the general user needs a few to load the operating system and a few working software that need speeding up.
