Buying Guide

Sound card

Not all sound cards are made equal. Since most motherboards support digital audio and surround sound inputs, it can get tricky to distinguish between average and high-end sound cards.

SupremeFX is one of the higher-end codecs, and it’s found on many mid-to-high level boards. Some enthusiast-level boards have integrated DACs and preamps, which will make a considerable difference if you are using high-end audio equipment.

Compatibility

Motherboards can be a bit tricky for new pc builders. Just because a motherboard has an AM4 socket does not mean it will support every AM4 socket processor. For example, all X470 based motherboards have the AM4 slot, but the X470 does not support AM4 socket Ryzen 5000 series CPUs.

There is a CPU support list for every motherboard, so make sure to check if your CPU is on that list before buying a motherboard.

RAM Speed

Most motherboards on the market can support up to 128 GB of RAM, but not all of them support high-frequency speeds.

This is one of those areas where manufacturers are known to cheap out, especially on budget boards. If you get high-speed RAM and use it with a motherboard that doesn’t support it, your PC will still work fine, but you will be losing up to 50% of performance.

Always check the specifications to make sure your motherboards support the RAM speed of your sticks.

Ethernet controller

Having a motherboard with the latest ethernet controller can be a detrimental factor to your internet browsing experience.

If you have access to fiber-optic internet, and you end up getting a board with an outdated gigabit controller, you will be limited to a max 1Gbps transfer speed.

Most mid-range motherboards have at least a 2.5 Gbit controller, while some enthusiast-level boards have top-of-the-line controllers which support transfer speeds up to 10Gbps.
