Expected Performance

Gaming Performance on the Base RTX 5080 16GB

Because the GPU is configurable, the live page presents base-configuration performance by experience tier rather than fixed FPS ranges — that same format is kept below rather than inventing numeric figures for a card that can change.

Game 4K Experience (Base RTX 5080) 1440p Experience (Base RTX 5080)
Call of Duty / Warzone Excellent, high-refresh capable Extremely high FPS
Fortnite Excellent with High/Ultra or competitive settings Excellent for high-refresh monitors
Apex Legends Excellent Extremely high-refresh capable
Cyberpunk 2077 Strong with DLSS and tuned ray tracing settings Excellent with high visual settings
Black Myth: Wukong Strong with appropriate DLSS settings Excellent
Forza Horizon 5 Excellent Extremely strong
Baldur’s Gate 3 Excellent Extremely strong
Starfield Strong Excellent
Microsoft Flight Simulator Strong, workload dependent Excellent high-refresh capability

This table matches the format and figures already published on the live page for the base configuration — carried over unchanged. Selecting a different GPU in the configurator will change these results.

FAQ

Common Questions About the Matrix Series Ryzen 9 9950X3D Custom Gaming PC

Can I Change the Ryzen 9 9950X3D CPU?

No. The Ryzen 9 9950X3D is the fixed processor and foundation of this specific custom-PC product — it’s what stays constant while you configure everything else around it. If you want a different CPU as your starting point, another Sirius custom or prebuilt product would be the better fit.

What Happens If I Don’t Change Any Configurator Options?

You get a complete, premium system as-is: Ryzen 9 9950X3D, RTX 5080 16GB, 32GB DDR5-6000, a 2TB NVMe drive, 360mm AIO cooling, a 1200W PSU, Windows 11 Home, and the Black Matrix case with 10 case fans — not a stripped-down shell that needs immediate upgrades.

Can I Choose a Different Graphics Card Than the Base RTX 5080?

Yes. The RTX 5080 is the base/default GPU, but additional graphics card tiers are available in the configurator — both lower-cost options if 4K performance isn’t your priority, and higher-VRAM options if you need more GPU memory for professional or AI workloads.

Why Does the Base Configuration Include a 1200W PSU for an RTX 5080?

NVIDIA’s reference RTX 5080 only requires an 850W system, so the 1200W PSU here isn’t a bare minimum — it’s deliberate headroom for future GPU upgrades, additional storage, and expansion, so the system isn’t designed around today’s minimum requirement.

Can I Add a Second or Third Storage Drive?

Yes. This platform supports separate selections for a primary, second, and third storage drive, which is useful for keeping Windows and applications separate from game libraries, footage, or long-term project storage.

Why Ryzen 9 9950X3D2 + RTX 5080 Work Together

The 9950X3D2’s 16 cores and AMD’s 3D V-Cache serve two different purposes at once. The extra cache keeps frame pacing tight in CPU-sensitive games, while the full 16-core count means gaming, streaming, and background applications can all run in parallel without competing for the same limited resources — this isn’t a chip that’s fast for gaming OR productive for work, it’s built to do both simultaneously.

The base RTX 5080’s 16GB GDDR7 buffer is matched to premium 4K gaming with real ray tracing headroom, and gives creator applications room to work with large scenes and high-res assets without hitting a memory ceiling. Neither component in this base pairing is oversized for the other.

Why This Custom Platform Simplifies Building Around a Fixed CPU

Building a fully custom PC from an open parts list means solving real compatibility questions yourself — which motherboard has the features you need, how much PSU headroom a given GPU actually requires, whether your chosen cooler fits the case, which M.2 slots share bandwidth. This platform removes that guesswork: every configurable option (GPU tier, motherboard, memory, storage, PSU) is pre-verified compatible with the fixed 9950X3D2 foundation, so you’re choosing based on what you want, not researching whether it’ll work.

The X870 Platform: What the Base Motherboard Actually Gives You

The Gigabyte X870 GAMING WIFI6 isn’t just a placeholder default — it includes dual USB4, 2.5GbE, Wi-Fi 6, and three M.2 storage positions, giving genuine expansion room even before you touch the configurator. If your use case needs different features (more M.2 slots, different networking, premium audio), the configurator lets you step up — but the base board itself isn’t a stripped-down starting point that forces an upgrade.

Memory and Storage: Configuring for Your Actual Workload

The base 32GB is a strong baseline for gaming and most creator work, but it’s worth being honest about when it’s not enough: large Premiere Pro or After Effects projects, complex Unreal Engine work, virtual machines, or heavy multitasking across several professional applications at once are where 64GB earns its place. If none of that describes your regular use, staying at 32GB doesn’t cost you gaming performance.

Storage works the same way — the base 2TB drive is a practical single-drive setup, but separating your OS/games drive from a dedicated media or project drive (the second and third storage options) genuinely helps once your footage, recordings, or project files start competing for space with your game library.

Is This Custom Platform Right for You?

Choose this build if:

  • You want premium 4K gaming as your starting point, with real headroom to personalize the rest
  • Your use case combines gaming with genuine creator, streaming, or development work — the 16-core foundation is built for that combination specifically
  • You’d rather choose from pre-verified compatible options than research compatibility yourself

Consider a different Sirius product if:

  • Gaming is your only use case and you don’t need 16 cores — a Ryzen 9 X3D configuration delivers excellent gaming performance without paying for cores you won’t use
  • You need more GPU memory than the base RTX 5080 offers for professional AI or rendering work — a higher-VRAM configuration or Sirius workstation product fits that better
  • Your workload needs more CPU cores or memory bandwidth than any single-GPU desktop reasonably supports — that points toward workstation-class infrastructure instead

More Questions About This Custom Platform

Does Changing the Case Color or Fan Color Affect Performance?

No — appearance options (case color, fan color, AIO color) are purely visual and don’t change the underlying hardware performance in any way.

If I Upgrade the GPU Later Myself, Does That Void My Warranty?

Installing compatible upgrades after purchase doesn’t automatically void the Sirius labor warranty — but damage caused by an incompatible component, improper installation, or a defective aftermarket part isn’t covered. Individual component warranties remain subject to their own manufacturer terms.

Do the Optional Accessories (Capture Card, Stream Deck, UPS) Get Installed by Sirius or Shipped Separately?

Components and accessories selected through the configurator are installed and tested as part of the completed system — you receive the finished configuration, not a base PC plus a separate box of parts.

How Do I Know What Size UPS I Need if I Add One?

UPS sizing should be based on your actual connected load (the PC, monitor, networking equipment, and anything else you want protected) rather than the PSU’s 1200W nameplate rating, since the system doesn’t draw anywhere near that continuously.

Is Windows 11 Home Enough, or Should I Upgrade to Pro?

Home covers gaming and general creator use well. Pro makes more sense if you need Remote Desktop hosting, BitLocker, or business/organizational administration features.

Does Adding a Third Storage Drive Slow Down the System?

No — additional NVMe drives don’t slow down existing storage; they simply add separate space, useful for keeping Windows, active projects, and long-term archives on different drives.

This is a custom platform — case color, cooling appearance, motherboard, memory, GPU, up to three storage drives, PSU, OS, and accessories are all configurable before checkout. Content above reflects the base add-to-cart configuration.
