ArsenalPC Gigabyte C301 GLASS Ryzen 7 9700X RTX 5080 128GB DDR5 4TB NVMe Liquid Cooled Gaming PC

System identity

This ArsenalPC desktop pairs an AMD Ryzen 7 9700X eight-core processor running at 3.8GHz with an NVIDIA GeForce RTX 5080 graphics card carrying 16GB of GDDR7 memory. The build targets 4K gaming and heavy creative workloads that demand both high single-thread speed and large frame buffers. Buyers who need more storage than the single 4TB NVMe drive provides, or who require a second graphics card for multi-GPU compute, should look elsewhere.

Graphics interface limit

The RTX 5080 connects through a PCI Express x16 slot, so its throughput is bounded by that lane width and the signalling rate of the platform. Workloads that saturate the bus with constant texture streaming or large dataset transfers will hit the ceiling of the x16 link before the GPU compute units become the bottleneck. Systems needing higher interconnect bandwidth for multi-GPU scaling cannot be served by this motherboard layout.

Capacity and headroom

128GB of DDR5 memory across four populated slots leaves no free DIMM positions for future expansion, while the 4TB NVMe SSD offers substantial space for modern game libraries and project files. The 1000W power supply delivers headroom for the liquid-cooled CPU and 16GB GPU under sustained load. Users planning to add further internal drives or upgrade memory beyond 128GB will need a different platform.
