Nebula GTRTX 5080 Gaming PC
The Nebula platform, tuned for high-refresh gaming. The AMD Ryzen 7 9800X3D paired with the NVIDIA GeForce RTX 5080 16GB, 32GB of T-Force DDR5 and a 2TB Samsung 990 PRO, held at temperature by an Arctic Liquid Freezer III 360mm loop inside the Lian Li O11 Dynamic EVO RGB.
This is a machine for 1440p at very high refresh rates and for 4K with ray tracing switched on, built from the same premium parts as our flagship. Assembled, tested and backed by our technicians in London.
Inside the Build
No filler parts and no surprises. Here is what each piece does and why it is in here.
AMD Ryzen 7 9800X3D
Eight cores, sixteen threads, and an extra layer of cache stacked directly on top of the chip. AMD calls it 3D V-Cache. It is the reason this processor sits at the top of almost every gaming chart.
Games constantly ask for small pieces of data. When that data is already in cache the answer is instant. When it is not, the processor waits on system memory and you feel it as a stutter. This chip holds far more of the game close to hand, which matters more than raw clock speed once you are chasing high frame rates.
It is also the right partner for the RTX 5080. At 1440p and high refresh rates the processor often decides how fast the game can go, and this is the chip that keeps the graphics card working at full pace instead of waiting.
GeForce RTX 5080 16GB
The second most powerful card in NVIDIA's RTX 50 Series, built on the same Blackwell architecture as the RTX 5090 with 16GB of fast GDDR7 memory.
Ray tracing lights a scene the way light actually behaves, with reflections and shadows worked out properly rather than faked. The RTX 5080 has the power to leave it switched on. DLSS 4 then renders the frame at a lower resolution, rebuilds it sharp using AI, and uses Multi Frame Generation to add extra frames in between, so you get the detail of high settings at frame rates that used to require turning things off.
16GB is comfortable for modern games at 1440p and 4K, and it handles video editing, 3D work and streaming alongside gaming without complaint.
Arctic Liquid Freezer III 360mm
A closed liquid loop. Coolant collects heat from the processor, carries it to a 360mm radiator, and three fans push it out of the case.
Arctic builds the radiator thicker than most coolers in its class, which gives the heat more surface to leave through, so the fans can turn more slowly for the same result. On AM5 it mounts slightly offset, placing the strongest cooling over the part of the 9800X3D that actually runs hottest. The practical effect is a processor that holds its top speed through a long session and stays quiet doing it.
A small fan built into the pump housing also moves air across the motherboard's power delivery, an area that liquid-cooled builds usually leave without direct airflow.
MSI MAG X870E Tomahawk WiFi
The board everything plugs into. Tomahawk is MSI's long-running enthusiast line, known for strong power delivery and heavy heatsinking, which matters when you are feeding a processor and a card of this calibre.
X870E is the top of the AM5 platform. PCIe 5.0 runs to both the graphics slot and M.2 storage, so there is a path forward for faster cards and faster drives as they arrive. Wi-Fi 7, Bluetooth and 5Gb wired networking are built in, and USB4 gives you 40Gbps connectivity for fast external drives and docks.
Multiple M.2 slots, four memory slots and generous USB provision mean adding storage, memory or peripherals later does not involve trade-offs.
32GB T-Force DDR5 at 6000MHz
Memory is where the machine keeps everything it might need in the next few seconds. 32GB is the sweet spot for a high-end gaming PC today, with room to spare beyond what games themselves ask for.
Play, stream, record, run Discord and keep a browser full of tabs open, and nothing has to fight for room.
Running as two 16GB modules in dual channel at 6000MHz, which is the speed the Ryzen platform is happiest at. Quick answers to the processor show up as fewer sudden dips in the middle of play. If your work grows, the board has two free slots ready for more.
Samsung 990 PRO 2TB NVMe
Samsung's flagship drive, reading at up to 7,450MB/s. Windows boots in seconds and games load in a fraction of the time older storage would take.
Open world titles stream scenery in as you move through it, so turning a corner quickly does not produce textures arriving late. Large video files scrub without waiting on the drive.
2TB holds a healthy library of large modern games at once, alongside Windows and your everyday files. When you want more, there are spare M.2 slots on the board ready for a second drive.
be quiet! Dark Power 14 1000W
Clean, steady power for everything above. 80 PLUS Titanium is the highest efficiency rating there is, a step above Platinum, meaning very little energy is wasted as heat, so it runs cool and costs less to leave on.
1000W gives the RTX 5080 generous headroom. Graphics cards can draw hard in short bursts, and a supply with real capacity to spare absorbs those spikes without the system deciding to restart itself. It is built to the ATX 3.1 standard with a native 12V-2x6 cable, so the graphics card is powered directly with no adapter in between, and there is room for a bigger card later.
Fully modular, so we only fit the cables this build actually uses, and as the name suggests, be quiet! tune the fan to stay near silent at everyday loads.
Lian Li O11 Dynamic EVO RGB
A dual chamber case, which means the power supply and the cable routing live in a separate compartment behind the motherboard tray. You see the components and none of the wiring.
Glass wraps the front and side with no pillar at the corner, so the whole build is on show from almost any angle. With cables out of the way, air moves through the case without obstruction, and that clear path is what keeps temperatures and noise down.
Ten ARGB fans come fitted as standard, working alongside RGB lighting built into the chassis itself, and all of it is adjustable through software.

Ultra · DLSS QualityA note on these numbers. Figures are averages drawn from published testing of this hardware combination and our own bench runs. Real frame rates move with the scene, the driver version, the game patch and your monitor, so treat these as a realistic guide rather than a guarantee. Titles marked DLSS or MFG use NVIDIA's AI upscaling and frame generation at the quality mode stated.
Whether you're battling in Call of Duty, climbing the ranks in Counter-Strike 2 or Valorant, exploring Cyberpunk 2077, Black Myth: Wukong or Starfield with ray tracing switched on, or racing through Forza Horizon 5, the Nebula GT delivers the performance to keep gameplay smooth, responsive and immersive at high settings.
The GeForce RTX 5080 brings NVIDIA's latest Blackwell architecture, combining full ray tracing with DLSS 4 Multi Frame Generation. It is at its best driving high-refresh 1440p panels at maximum settings, and it is more than capable at 4K, where DLSS keeps demanding titles smooth.
With 32GB of T-Force DDR5 6000MHz memory, applications stay responsive while streaming, recording and chatting alongside a game. The Samsung 990 PRO 2TB NVMe drive cuts boot times, game loading and level transitions down to a few seconds, so you spend less time waiting and more time playing.
Outside gaming, the same specification handles 4K video editing, 3D rendering and streaming with ease, and the X870E platform leaves plenty of room to add memory or storage as your projects grow.
