For anyone who appreciates quality audio, getting a performant sound card is essential. Whether you’re building a computer or simply need an upgrade to your sound, a high-quality sound card is the way to go. Nowadays motherboards are advanced enough to offer a decent sound solution, but many people still prefer a dedicated audio component to obtain the best sound performance in games, movies, and music.

The main reason why you need to consider getting a capable sound card is that of the stress on the motherboard which causes RFI noise that affects the audio quality. When you leave the audio processing to the sound card you can benefit from a superior sound, but there are other advantages too. They allow for better connectivity and to power more demanding headphones. If you also take into account the fact that many sound cards come with their own special software, it becomes clear that sound cards are must-have components for anyone who wants a more clear and customized sound. You might also be interested in our articles about the best computer speakers and the best USB microphones.

There are both internal and external sound cards available on the market and they all come with their ups and downs. Making sense of them requires a guide that provides you with the most important features to analyze. To find your ideal sound card you need to be aware of:

1. Matching your speakers/headphones

There’s no point in getting a high-end sound card unless you have the gear to keep up. This is why most onboard sound cards have average audio performance. Most users don’t really have the right equipment to notice the difference anyway. If you own high-quality speakers or headphones then you should definitely look at a sound card that seems to match their level. You will be able to truly benefit from the superior audio quality of a premium sound card if your equipment is able to effectively reproduce the sound.

2. Internal vs External

Audiophiles who travel often with their laptops should obviously consider an external sound card over an internal model. For everyone else, internal sound cards should take priority because they’re more responsive and overall the sound performance is better thanks to the difference in connectivity speed between PCIe and USB.

3. Software/hardware compatibility

The final thing worth keeping in mind is if your desired sound card works well with your operating system and if there are any hardware compatibility issues. Some motherboards lack the needed PCIe slots and sometimes you might encounter difficulties fitting the new component in a computer case. This is the case for internal units. Those who decide to get an external sound card should only focus on having a free USB port.

With this out of the way, let’s check the individual reviews for the most cost-effective sound cards on the market. This is a selection that’s varied in terms of types of cards, features, and price. Anyone on the market for a high-quality sound card should find in here something worth the money to fit their particular needs.
