You game at 4K and demand 144fps+ in every title without compromise. You appreciate showcase-tier aesthetics — the OLED-display AIO, LCD-screen fans, and panoramic Lian Li Vision case make every angle of this build visually striking. You stream at 4K60 while gaming. You run demanding creative workloads — video editing, 3D rendering, AI/ML — alongside gaming. Budget is not the primary constraint and you refuse to compromise on any component. Skip this if: Your primary use case is content creation rather than gaming — the Ryzen 9 9950X3D + RTX 5090 build offers 16 cores at the cost of pure gaming framerate advantage. For pure 1440p gaming, the Ryzen 7 9800X3D + RTX 5070 at $3,799 captures most of the gaming performance for a fraction of the cost. Why This CPU + GPU Pairing The Ryzen 7 9800X3D is AMD's gaming-king CPU — 8 cores of Zen 5 architecture with second-generation 3D V-Cache that makes it the fastest gaming chip available. Paired with the ASUS ROG Astral RTX 5090 (32GB GDDR7, Blackwell architecture), this combination extracts every possible frame from any game at any resolution. The Astral variant of the 5090 is among the most premium 5090 cards available — quad-fan cooler, reinforced VRM, factory overclock, and an LCD display for status. 64GB of DDR5 ensures no memory bottleneck in any workload, and the MONTECH Century II 1200W ATX 3.1 PSU (rated Cybenetics Platinum for efficiency) provides clean modern power delivery with the native 12V-2x6 connector. The Lian Li HydroShift II OLED Curved AIO and 5 UNI FAN TL LCD fans turn the cooling system itself into a visual centrepiece, all housed in the Lian Li Vision panoramic showcase case. Upgrade Path This is as future-proof as a gaming PC gets in 2026. The AM5 socket supports future Ryzen CPU generations with a BIOS update. The RTX 5090 is the current GPU ceiling — future GPU upgrades will be available when NVIDIA's next architecture launches, and the 1200W Cybenetics Platinum PSU has the headroom for anything. RAM is expandable beyond 64GB. The Lian Li Vision has clearance and airflow for any GPU available today and in the next generation.

Yes — the 9800X3D is the fastest gaming CPU available today thanks to its 3D V-Cache. Paired with the RTX 5090, it extracts maximum framerates from the GPU at any resolution, including CPU-bound scenarios at 1080p and 1440p where many other flagships would bottleneck. What resolution does this PC target? All resolutions — 1080p (450fps+), 1440p (350fps+), and 4K (140–180fps in demanding AAA titles, 400fps+ in competitive games). This is the only system where 4K 144Hz is genuinely achievable across every modern game without compromise. What makes the ASUS ROG Astral RTX 5090 special? The ASUS ROG Astral is one of the most premium RTX 5090 variants available — a thick quad-fan cooler design, factory-overclocked clock speeds, reinforced VRM, and an LCD display on the side that shows temperatures, fan speeds, or custom artwork. It runs cooler and quieter than reference RTX 5090 cards under sustained loads. What is the Lian Li HydroShift II OLED Curved AIO? The HydroShift II OLED Curved is one of the most premium AIO coolers on the market — a 360mm liquid cooler with a 6.67-inch 2K 60Hz curved OLED display built into the pump block. The screen can show system stats, custom artwork, or animations, making the cooler the visual centrepiece of the build. Tell me about the Lian Li Vision case and the fan setup. The Lian Li Vision is a premium dual-chamber showcase case with curved panoramic tempered glass for an unobstructed view of the internal components. The 5 UNI FAN TL LCD fans each have a small LCD display, and the 3 ARGB fans complete the lighting and airflow. The result is a build that looks as impressive as it performs. Can this PC handle game streaming and content creation? Absolutely. The 9800X3D excels at gaming while still providing 8 cores / 16 threads for OBS streaming, recording, and content creation. The RTX 5090's 32GB GDDR7 also excels at 4K video editing, 3D rendering, and AI/ML workloads. Does this come with Windows installed? Yes. Windows 11 Pro is pre-installed and activated. The PC is ready to use immediately out of the box. How long does shipping to Canada take? Orders placed by 4 PM ship same day or are available for same-day pickup at our Vaughan store.
