The large 64 GB memory capacity supports multitasking, streaming, and editing large files without frequent memory bottlenecks. The 2 TB SSD reduces load and boot times compared with traditional drives and provides substantial local storage for games and projects. Supplied without an OS, the system is ready for custom software setups and can be optimized for specific workflows.

Suitable for

• High-resolution gaming and competitive esports
• VR and real-time 3D rendering
• Video editing, 3D modelling and content creation
• Multitasking, streaming and simultaneous application use

When it may not be suitable

The system is not supplied with an operating system, so it may not be suitable for users who need a ready-to-use PC out of the box or who are not comfortable installing an OS and drivers. Users with only basic office or web tasks may find this level of performance unnecessary and could opt for a lower-specification, more cost-effective desktop.

How to use

Install your preferred operating system and the latest motherboard and graphics drivers to ensure optimal performance. Connect peripherals such as monitor, keyboard, mouse and headset, and configure display settings in the OS and GPU control panel to match your target resolution and refresh rate. For gaming, use the game or GPU settings to balance quality and performance; for content creation, install required applications and set scratch disks and project locations to the SSD for faster access.

What to consider before purchase

• Plan for OS installation and driver setup, and confirm software compatibility with the selected processor and GPU.
• Ensure your monitor and peripherals support the desired resolution and refresh rate to take full advantage of the GPU.
• Check physical dimensions and power requirements to confirm the system fits your workspace and any transport or power constraints.

Usage recommendations

Keep system drivers and firmware up to date, use a reliable backup strategy for important data, and monitor temperatures under load to maintain stable performance. For best results in demanding workloads, enable appropriate cooling profiles and, where relevant, use the SSD as the primary drive for active projects and games.
