Why bother with two PCs?
Ever wondered if juggling two PCs is really worth the extra desk space and cables? For serious streamers and content creators, the answer is a resounding yes. Let me break down why a dual PC setup might be exactly what your streams have been missing.
Your high performance gaming PC gets to focus solely on what it does best – rendering those gorgeous game worlds at silky-smooth frame rates. Meanwhile, your streaming PC handles all the broadcasting heavy lifting like encoding, managing your alerts, and keeping your chat visible. This separation of duties makes a world of difference.
Many streamers report gaining a substantial 20-30% boost in frames per second after switching to a dual PC configuration. This improvement becomes especially noticeable when you're deep in the action of CPU-hungry titles like battle royales or vast open-world trips. Your gaming PC high performance remains dedicated to delivering the best possible gaming experience without sacrificing a single frame to streaming tasks.
Beyond just performance, there's also peace of mind. If one system hiccups (and we all know technology occasionally does), your other PC can keep things running. This redundancy means fewer awkward stream interruptions and a more professional broadcast overall.
As games continue to push technical boundaries year after year, a dual PC setup also gives you more flexibility to upgrade components strategically. Instead of constantly chasing the latest all-in-one powerhouse, you can target upgrades specifically for gaming or streaming as needed.
"Two computers can be better than one, especially when it comes to streaming games," as many streaming veterans will tell you. "Your high performance desktop pc stays focused on running your game flawlessly, while your streaming PC handles everything else."

Dual PC Streaming Audio Setup Elgato: Hardware & Cabling Essentials
Let's talk about the beating heart of your dual PC streaming setup – the capture card. Think of it as the bridge connecting your gaming universe to your streaming world. Elgato's family of capture cards offers several fantastic options to fit different needs:
The Elgato HD60 S+ and HD60 X are perfect if you're using a laptop as your streaming PC, connecting via USB 3.0 with plug-and-play simplicity. If you prefer something more permanent, the Elgato HD60 Pro and its MK.2 successor slide into a PCIe slot on your streaming PC, rewarding you with noticeably lower latency. For content creators who demand the absolute best, the Elgato 4K60 Pro MK.2 handles 4K capture with impressive fidelity.
While these capture cards seamlessly transport both video and audio from your gaming PC to your streaming PC, the real art comes in routing your voice and other audio sources. This requires a bit of planning, but I promise it's worth the effort!
Dual PC Streaming Audio Setup Elgato Hardware Checklist
Building the perfect dual pc streaming audio setup elgato starts with having the right gear. For your gaming PC, you'll want a modern GPU with an HDMI output to feed your capture card, along with a DisplayPort connection for your main gaming monitor (especially important for high refresh rate gaming). Don't forget about headphone output or front panel audio jacks for routing game sound.
Your streaming PC needs either an available PCIe slot for internal capture cards or a USB 3.0 port for external models. CPU power matters here – while a quad-core processor is the bare minimum, six or eight cores will give your stream that buttery smooth encoding that viewers love. Make sure you have audio inputs for your microphone and any additional sources too.
The supporting cast includes your Elgato capture card, some 3.5mm TRS cables for analog audio connections, and ideally a USB microphone like the Elgato Wave:3 (or an XLR mic with an interface if you're feeling fancy). One often-overlooked hero in this setup is a ground loop isolator – this $10-15 device can be the difference between crystal clear audio and an annoying buzz that drives viewers away.
A high performance desktop PC for each role ensures the best results, with your gaming rig prioritizing GPU power and clock speeds while your streaming machine benefits from those extra CPU cores for encoding.
Video Cloning at 144 Hz While Sending 60 Hz to Card
Here's where things get interesting. Most gamers crave those silky smooth 120Hz, 144Hz, or even 240Hz refresh rates, but most Elgato capture cards only accept 60Hz input. How do we solve this puzzle? Display cloning with different refresh rates!
Connect your gaming monitor via DisplayPort to enjoy those high refresh rates, then connect the Elgato via HDMI. In your Nvidia Control Panel (or AMD equivalent), select "Clone" mode under multiple displays. The magic happens when you create custom resolutions – one for your primary monitor at 1920x1080 @ 144Hz and another for the Elgato clone at 1920x1080 @ 60Hz. Set both displays to "No scaling" with "Perform scaling on: GPU" for best results.
This clever configuration lets you build high performance gaming PC setups that don't compromise. You'll enjoy that competitive edge from high refresh gaming while sending a perfect 60Hz signal to your streaming PC. It's truly the best of both worlds!
Routing Game Audio to Stream PC
There are three main paths to get your game audio from your gaming PC to your streaming PC, each with its own advantages:
Method 1: Elgato Sound Capture is the easiest approach – install it on your gaming PC, select the "PC Gaming" feature, and configure output to both your headphones and the Elgato device. Your game audio travels through HDMI to your streaming PC without any extra cables.
Method 2: Wave Link Stream Mix works beautifully if you're using a Wave microphone. Install Wave Link 1.9+ on your gaming PC and configure your audio sources. The Stream Mix output shows up as a recording device in Windows – right-click it, open Properties, go to the Listen tab, check "Listen to this device" and select your HDMI output. Clean and efficient!
Method 3: Analog Line-Out offers maximum compatibility. Connect a 3.5mm cable from your gaming PC's headphone jack to your streaming PC's line-in port, with a ground loop isolator in between to banish any buzzing. Then configure Windows to use this input in OBS or your preferred streaming software.
As Elgato's documentation suggests, "connecting audio to the streaming PC ensures the highest possible audio quality" by minimizing compression and potential quality loss.

Sending Mic to Both PCs
For those moments when you need your voice for both in-game chat and your stream, there's a simple solution.
If you're using a USB microphone like the Elgato Wave:3, connect it directly to your streaming PC via USB. Then run a 3.5mm cable from the microphone's headphone output to your gaming PC's line-in port. Set this line-in as your recording device in Windows sound settings, and voilà – your voice is available for Discord and in-game chat without complicated software.
For the XLR enthusiasts with audio interfaces, connect your interface to the streaming PC via USB, then use the interface's direct monitoring or headphone output with a 3.5mm cable to your gaming PC's line-in port.
Modern microphones with AI-driven performance features reduce latency and improve voice clarity. The latest generation includes handy features like touch-sensitive mute buttons and built-in pop filters that make dual PC setups more reliable.
As Elgato notes, "Wave:3 can be used in a two PC setup, where the gaming PC is only gaming, and a streaming PC is dedicated to streaming." This separation gives you the best performance for both gaming and broadcasting, ensuring your audience enjoys a professional stream while you dominate in-game.
Software Mixers, Sync & Latency Fixes
Let's explore the heart of your dual PC streaming audio setup Elgato - the software mixers that bring everything together. Think of these as your virtual sound control room, where you'll direct every audio source exactly where it needs to go.
Dual PC Streaming Audio Setup Elgato with Wave Link 1.9+
If you're using an Elgato Wave microphone, you're in luck! Wave Link (version 1.9 or newer) makes this process surprisingly straightforward:
Install Wave Link on your gaming PC and set up your audio sources like your game, Discord chat, and music. Once configured, you'll notice the Stream Mix appears as a recording device in Windows. Right-click it in Sound Control Panel, head to the Listen tab, and check "Listen to this device." Then select your HDMI output as the playback device and click Apply.
What's great about this method is its simplicity - no extra cables or complex routing! Your AI-ready gaming PC benefits from Wave Link's smart processing features like noise reduction without stealing precious resources from your gaming performance. The Stream Mix hardware output feature works beautifully with any capture card, not just Elgato models.
Voicemeeter Banana Cheat Sheet
Don't have a Wave microphone? No problem! Voicemeeter Banana is a powerful (and free!) alternative that many streamers swear by:
After installing Voicemeeter Banana and Virtual Audio Cable on your gaming PC, set your Windows default playback to "VB-Audio VoiceMeeter VAIO." Then configure your hardware outputs - A1 for your headphones, A3 for your HDMI output to the capture card, and set up your mic input if it's connected to your gaming PC. The magic happens when you route your audio to both outputs by clicking the corresponding buttons.
Driver settings matter too - WDM offers better compatibility but might have higher latency, while KS/ASIO provides the lowest latency but might not work with all devices. Buffer settings are a balancing act between responsiveness and stability - lower values around 256 samples give less delay but might cause crackling, while higher values around 1024 samples are more stable but introduce more delay.
For an excellent walkthrough of all these settings, check out this comprehensive Voicemeeter tutorial.
Keeping Audio & Video in Sync
Nothing ruins a stream faster than out-of-sync audio. Here's how to keep everything perfectly aligned:
Match your sample rates across all your devices - either all at 44.1 kHz or all at 48 kHz. Check both Windows sound settings and OBS audio settings to ensure consistency.
To measure your capture card delay, open a stopwatch website on your gaming PC and compare what you see on your gaming monitor versus what appears in OBS. The difference is your video delay.
Then apply a sync offset in OBS by right-clicking your audio sources, selecting Properties, and adding a "Sync Offset" in milliseconds. Positive values delay audio, while negative values advance it. For most Elgato capture cards, you'll typically need between 650-900ms of offset.
Modern capture software with AI-improved visuals can help detect sync issues, but a manual touch usually gives the best results. Take your time here - perfect sync makes your stream look truly professional.
Common Audio Issues & Fast Fixes
Even the best setups run into trouble sometimes. Here are quick solutions to common headaches:
That annoying buzzing or humming is almost always a ground loop - adding an inexpensive ground loop isolator between your analog connections usually fixes it instantly.
If you're hearing an echo, you're probably creating an audio feedback loop by monitoring the same audio twice. Check your monitoring settings in OBS and Windows.
No audio in OBS? Double-check that you've selected the correct audio devices in both OBS and Windows default devices.
Many streamers find their USB gaming headset sounds worse than expected because of digital compression. Consider using an analog connection or upgrading to a better audio interface for clearer sound.
Audio delay and crackling usually come down to buffer settings - if you hear delays, reduce your buffer size; if you hear crackling, increase it.
Your AI cooling solutions in a modern gaming PC help maintain stable temperatures during intense streaming sessions, which prevents the thermal throttling that can cause annoying audio dropouts.
Many gaming headsets don't pass through surround sound via Voicemeeter, and some have proprietary drivers that fight with audio routing software. For the absolute best quality, consider a separate headphone and microphone setup.
Taking the time to properly configure your audio mixing software is what separates amateur streams from professional broadcasts. With these settings dialed in, your high performance gaming PC will deliver crystal-clear audio that perfectly complements your gameplay.
