So you are planning to invest in a premium VR headset? You are going to need a decent gaming machine to go with that. The MSI Vortex is a compact, high-performance gaming machine with an Intel Core i7 6700K processor, up to 64 GB of DDR4 memory, SSDs, and dual NVIDIA GeForce GTX 980 GPUs in SLI. The machine is ready to be upgraded and expanded. It comes with Thunderbolt 3 and other connectors.
MSI Vortex has a 360-degree Silent Storm Cooling technology and 450W 80 plus Gold power supply. It can support up to 6 video outputs and is ready for 4K. Not cheap though.
