Why buy a more expensive motherboard?

[MrReptilian]

Why? Whats the difference, and why would a 500 dollar mobo be better than a 100 dollar one?

features ... better sound card chips, better onboard network cards, more connectivity (more usb 10g on the back for example)

 

higher vrm quality (the dc-dc converter circuit which powers the cpu) allowing for higher overclocks, or making it possible to support 12-16 core processors without throttling down after 10-20 minutes because the vrm overheats.

So, say for a budget build, going for a more expensive mobo would be unnecessary?

Yeah, if you don't know that you need the expansion options you probably don't need them. Honestly most people can get away with a pretty entry level board as long as it's compatible with the CPU you are looking at. I personally would go a tiny bit above bargain basement just to get an extra 2 RAM slots and a second x16 PCIe slot (even if it's wired for x8) purely for a bit of expansion piece of mind.

Thanks, i guess i'll just stick to my a320m-k for the time being

Sometimes, it's for better VRM, more SATA ports, more USB3.0 or even USB 3.1 Gen2 ports, better components (Japanese capacitors and such), better cooling, etc, just overall better board for OC'ing runs cooler. I had gotten the GB X570 Aorus Xtreme because it doesn't have a small chipset cooler like the others, has heatpipes running through the board to cool all major components, heck, even my NVMe M.2 drive doesn't exceed 45C (using one of the mobo's NVMe M.2 shields/heatsinks).
