| Shielding | Copper/Gold plating |
| Interface | PCIe x1 |
The EVGA Nu Audio Pro offers a sweet spot in the market, delivering sound quality that rivals cards twice its price. During my evaluation, I found the imaging—the ability to pinpoint where sounds originate in a 3D space—to be exceptionally accurate. It’s less flashy than the Creative series, focusing instead on pure, transparent audio reproduction. If you do a mix of professional audio editing and gaming, this card handles both with finesse. While it doesn’t have the extensive “gaming effect” software that some users prefer, the hardware itself is superior to almost any stock sound solution you’ll find on a motherboard. It bridges the gap between consumer gaming gear and professional studio hardware. One minor drawback is that the software interface feels slightly dated compared to the modern UI of its competitors. If you strictly want pre-set “gaming modes,” this card might require more manual tuning, but for those who value balanced, natural sound, this is the best value available.
- Highly balanced, neutral audio profile
- Excellent build quality with premium shielding
- Great performance in both music and games
- Software interface lacks modern polish
- Fewer “gaming-specific” audio presets
Creative Sound Blaster Audigy FX View on Amazon
| SNR | 106dB |
|---|---|
| Resolution | 24-bit / 192kHz |
| Channels | 5.1 |
| Form Factor | Half-height/Low-profile |
| Interface | PCIe x1 |
The Audigy FX is a no-nonsense, budget-friendly solution for those whose onboard audio has failed or simply sounds muffled. It doesn’t offer the high-fidelity DACs of the more expensive cards, but in my testing, it did provide a cleaner, more consistent output than many mid-range stock motherboards. It’s perfect for someone using a basic 5.1 speaker system or an entry-level headset. The SBX Pro Studio software is surprisingly capable, allowing you to tweak EQ and surround settings to make your games feel a bit more immersive. That said, don’t expect a transformative audio experience if you are already using a high-end motherboard with decent built-in shielding. The limitations become apparent when driving higher-impedance headphones, where the power just isn’t there to drive them to their full potential. This is strictly a “get the job done” card for those on a tight budget who need reliable connectivity and decent surround sound virtualization for casual gaming.
- Extremely affordable
- Compact size fits most small-form-factor builds
- Solid software suite for the price
- Lacks power for high-impedance headphones
- Limited noise isolation compared to premium cards

The ASUS Strix Raid DLX brings a different flavor to the table with its aggressive gaming-centric focus. The “Raid” mode, which can be toggled via the included controller, allows you to save specific audio settings and activate them instantly mid-game—perfect for switching between different audio profiles depending on the match. In my testing, the sound profile was slightly warmer than the Creative alternatives, which some players prefer for longer gaming sessions to avoid listener fatigue. The build quality is exceptional, featuring a backplate that adds rigidity and helps with shielding against component heat. While I found the software interface to be a bit more complex to navigate than the Sound Blaster software, the sheer level of customization available is a massive plus for power users who love to tweak every frequency. It’s an excellent choice for users who want a high-performance card that feels integrated into the overall aesthetic of a high-end gaming PC.
- “Raid” mode is excellent for on-the-fly audio adjustment
- Warm, non-fatiguing sound profile

Frequently Asked Questions
Will a PCIe sound card improve my microphone quality during voice chat?
Yes, many high-end PCIe sound cards include dedicated hardware for microphone processing. By using a sound card, you bypass the potentially noisy onboard mic input of your motherboard, often resulting in a cleaner, clearer voice capture. For users of high-quality XLR or analog headsets, the improved pre-amp section on cards like the AE-9 can significantly reduce the background “hiss” often picked up in discord or during live streams.
How does a dedicated sound card compare to a USB external DAC?
Internal cards offer the advantage of being physically shielded inside your PC case, which is great for space saving and direct motherboard integration. However, external USB DACs provide the benefit of being completely removed from the electromagnetic interference inside your tower. If your PC has poor internal shielding, an external device might technically offer a cleaner signal, but most modern high-end PCIe cards have excellent shielding that makes this distinction negligible for gaming.
Is it a mistake to install a sound card right next to my graphics card?
This is a common concern, but in most cases, it is fine as long as there is some physical gap. Avoid placing the card in a slot that completely chokes the fans of your GPU. If your motherboard has a slot further away from the GPU, use that one to minimize the chance of electromagnetic interference, though modern cards are usually well-shielded against this.
Which card should I choose if I play competitive shooters like Valorant or CS2?
For competitive shooters, I recommend the Creative Sound Blaster AE-7. Its virtual surround processing is incredibly precise, allowing you to track enemy footsteps and sound cues with pinpoint accuracy. The sound profile is tuned to emphasize mid-range frequencies, which helps clear out unnecessary “noise” to reveal critical audio information. It is effectively the same performance as the flagship AE-9, just without the unnecessary premium features that don’t impact competitive performance.
Should I wait for a sale to buy a high-end sound card?
Sound card prices are relatively stable, but they do see significant dips during major sales events like Prime Day or Black Friday. Because these are enthusiast-tier components, they aren’t replaced annually like GPUs. If you find a deal on the AE-7 or AE-9, it is almost always worth grabbing immediately, as the audio quality improvement is a “buy it once, use it for years” type of investment.
Final Verdict
If you are a serious audiophile or streamer, the Creative Sound Blaster AE-9 provides the best total package. For competitive gamers who want professional results without the flagship price, the AE-7 is the smartest choice. If you are budget-constrained but need to fix noisy onboard audio, the Audigy FX is a solid, cost-effective entry point. Regardless of the card you choose, the transition from stock audio to a dedicated PCIe solution is one of the most noticeable upgrades you can make for your gaming experience. Expect this category to continue focusing on better shielding and simplified software interfaces in the coming years.
