A liquid-cooled desktop with a 12-core Ryzen 9 9900X3D, 64GB DDR5, 2TB NVMe and Radeon RX 9070 XT graphics for gaming and workstation tasks
This system combines a 12-core Ryzen 9 9900X3D processor with a Radeon RX 9070 XT graphics card and 64GB of DDR5 memory. It ships with Windows 11 Pro and a 2TB NVMe SSD for fast boot and load times. The 240mm liquid cooler keeps the CPU stable under sustained workloads.
The GPU connects through a single PCI Express x16 slot, so adding a second discrete card is not supported. The motherboard provides four M.2 connectors and two SATA 6Gb/s ports for additional storage expansion. Rear I/O includes USB4, 10Gbps and 5Gbps USB ports plus 2.5Gb Ethernet and Wi-Fi 7.
The Ryzen 9 9900X3D delivers 12 cores and 24 threads with a maximum boost clock of 5.50 GHz. Its large 128MB L3 cache benefits both gaming frame rates and compute tasks. Buyers who need more than 12 cores or a different socket should consider other platforms.

The board has four slots and supports up to 192 GB; 64 GB is ample for gaming and most creative work, while 192 GB suits heavy virtualization or large dataset workloads.
The 12-core Ryzen 9 9900X3D can boost up to 5.50 GHz across its 24 threads, so sustained heavy tasks run well above the base frequency.
The Radeon RX 9070 XT connects via a full x16 lane, giving the GPU unrestricted bandwidth for 4K gaming and compute tasks.
