Rig name: PC cheaper than a VR headset.
Cpu: i3-2120 3.3GHz
Gpu: GTX 960
Ram: 2x4gb DDR3
Score: 3.3
Tried overclocking GPU just for this. Although the overclock limit was quite disappointing (+35 MHz core clock, +450 MHz mem. clock; didn't try going above core voltage +30mV), it bumped the score to ~4. OK score, wasn't planning on using VR on this PC
