The DCG Horizon is the standout choice in Direct Computers’ SteamOS gaming range, combining seriously powerful hardware with the simplicity of a console-style gaming experience. Designed for enthusiasts who want high-end performance without the usual complexity of setting up a gaming PC, the Horizon is an impressive all-round package.
At the heart of the system is AMD’s Ryzen 7 9800X3D, paired with an AMD Radeon RX 9070 XT 16GB, 32GB of DDR5 memory and a generous 2TB NVMe SSD. It’s a specification built with demanding modern games in mind, and Direct Computers positions the system as a 4K gaming machine.
Built for 4K Gaming
The Horizon’s biggest attraction is its combination of high-end CPU and graphics performance. The Ryzen 7 9800X3D gives the system plenty of processing power, while the RX 9070 XT’s 16GB of dedicated graphics memory provides the headroom you want from a modern enthusiast gaming PC.
That makes the Horizon particularly appealing to gamers with a 4K monitor or TV who want to push image quality and performance without having to compromise on settings.
The 32GB of DDR5 RAM is another welcome inclusion. It gives the system plenty of memory for modern gaming and multitasking, while the 2TB NVMe SSD provides considerably more room for a large Steam library than many gaming PCs in this price bracket.
SteamOS Changes the Experience
Hardware is only half the story here. What makes the DCG Horizon different is the inclusion of SteamOS.
Instead of booting into a conventional Windows desktop, SteamOS is designed around gaming. You can access your Steam library through a familiar, controller-friendly interface, making the Horizon particularly well suited to living-room gaming.
Connect it to a TV, pick up an Xbox or PlayStation controller and the experience is much closer to using a traditional games console — but with the considerable performance and flexibility of a full desktop PC. Direct Computers also states that its SteamOS systems support popular controllers and can be connected to a TV via HDMI.
For anyone who loves the convenience of console gaming but wants access to the wider PC gaming ecosystem, that combination is arguably the Horizon's biggest selling point.
Ready to Go Out of the Box
Another advantage is that the Horizon arrives with SteamOS pre-installed, so there is no need to spend time installing an operating system and configuring the machine before getting started.
Direct Computers says its SteamOS PCs are built and tested in the UK, fully stress tested before dispatch and covered by a three-year warranty. The company also offers UK-based technical support.
That makes the Horizon an attractive option for gamers who want the benefits of a custom-built gaming PC without necessarily wanting to build or configure one themselves.
The Verdict
The DCG Horizon is the SteamOS PC to choose if performance is the priority.
Its Ryzen 7 9800X3D, RX 9070 XT 16GB, 32GB DDR5 and 2TB NVMe SSD give it the hardware credentials expected from an enthusiast gaming system, while SteamOS provides a wonderfully straightforward way to access your games.
It is particularly compelling for 4K gaming and living-room setups, where the combination of powerful PC hardware, controller support and a console-inspired interface really comes into its own.
Overall: a powerful, polished and refreshingly simple way to enjoy high-end PC gaming.
Best for: Enthusiast gamers, 4K gaming, living-room setups and anyone who wants PC performance with a console-style experience.
