So let's look at https://www.reddit.com/r/PCMasterRace/wiki/builds
You can go up the list from the basics and end up with a nice gaming PC. So far I've yet to find a VR PC to be the same as a good gaming PC.
Hello there
I am finally ready to build my own computer and I want it to have the capabilities to run Vr fairly well. I have never built a computer before and thus have no idea if getting the new Titan X Pascal is worth it or GTX 1080/1070 instead. That was just an example and thus I would really appreciate some help in getting a good VR computer going. As VR itself is 700+ already I would like to save where possible though I understand the PC needs to be at a certain level.
Thank you for your help
