I don't pick up my headset until tomorrow, but I suggest you consider the number of CPU cores because that should be a significant factor for the multiple tasks MR has to handle beyond the main package or game you are running. A Ryzen would be good value for that. I would add the best vid card you can muster. So a Ryzen with a GTX 1080 would be good as a 1080ti or Titan has a bit of a premium on the price.
