I find this news piece very interesting:http://www.roadtovr.com/amd-creates-vr- ... t-quantum/
AMD creating a designed-for-VR-PC that is just a little box. I think they're on the right track, this is possibly the future direction of PC rigs. No more the ATX form factor, but you buy a cube/rig from AMD or nVidia, because after all in the future the most important aspect of any PC will be the rendering capabilities for virtual reality purposes.
I'm pretty sure AMD and nVidia would surely like to take over this market, instead of leaving it as it is now where they only make the chips on the video cards. The GPU companies are gonna get huge.
