Since late 2025, thanks to the AI boom, we’ve seen prices skyrocket for RAM, video cards, and now storage, making building or buying a PC today much more expensive than it was. Where you might, in the past, spend more on mid-range or even a premium-class motherboard, now that build budget is probably going to some other piece of high-priced hardware.

So, where can you save money without losing performance? One of those areas is the motherboard. For the latest-generation Intel and AMD boards, prices range from wallet-emptying $900 to $1,200 for Asus, Gigabyte, and MSI flagships, down to around $90 across the three primary chipsets (Intel Z890/B860/H810 and AMD X870E/B850/B840). There are lesser desktop chipsets from both camps – H810 for Intel and B840 for AMD. And although these motherboards are entry-level and cost less, they’re mainly meant for office use, everyday computing, or budget-oriented PCs. They’re essentially for those who really don’t need a ton of connectivity but still want the benefits of the latest platform, whereas others are more feature-rich and capable.
