I have built every computer I've used since I was eight. Motherboards are still my least favourite component to buy. This video helps break down what to look for in a main board.
When you're buying a motherboard, there are lot of things to consider. You need to look at long-term upgrade capabilities (don't get stuck with a mobo that maxes out at 8GB of RAM like I did in 2014), support for esoteric features like dual graphics cards, on-board ports and more.
When it comes to buying motherboards, there's no one right answer but this video covers more features for you to consider than most people could ever need. Pick out the ones that sound interesting to you and focus on those. If you find all of this overwhelming, you can also check out our guide to building the best PCs for different budgets.
