I'm helping someone build a VR ready computer. He has $1200 to spend, and I'm not new to building rigs, but I've never done a VR ready one. So was hoping to get a smarter/more knowledged set of eyes on the general specs I'm suggesting to him before I convince him to commit this amount of money. Any suggestions are welcome.

Build below:

VR is generally not particularly CPU-intensive, and much of the content is not well threaded.

A Core i5 (or Ryzen 3) thus makes more sense for VR than a Core i7 or Ryzen 5. If you have money for upgrades, it's better spent on GPU horsepower. Or even better, keep it and spend it later on VR content or maybe in a couple years on a gen 2 VR headset.

Swapping in a better power supply, more storage for the money, and some cheaper but basically just as good options for CPU cooler and memory, here's the build I would suggest:

VR really does perform best when it's not competing for CPU resources, so would certainly point you in the direction of looking at more threads:

Considering the advice here is all over the map, I thought I'd link this for a bit more of an in depth answer:

Steve certainly can write a book about testing and methodology:

http://www.gamersnexus.net/guides/2871-amd-vs-intel-vr-cpu-benchmarks-with-vive-and-rift

To clarify my own build suggestion: I don't think you really need a 6c/12t CPU for good VR, but considering the price-to-performance, would strongly consider it over the Intel 4-core options.

Note that the 7700K is generally slightly better than the R7 1700 in those tests, despite the latter having twice as many cores and way more multithreaded performance. That's a good illustration of the fact that current VR content really doesn't rely on multithreaded performance.

They're both pretty much at the performance cap all the time though. If they also had CPU load in the graphs, you'd see them both having lots of headroom left. That's why you can easily step down to a Core i5. Or probably Ryzen 3, when it arrives.

Meanwhile, the money saved on the CPU can be put to good use upgrading the GPU. Either to increase the game's graphics settings, or to increase the supersampling.

Ryzen 5 isn't any better than Ryzen 7 in games. But they're both pretty close to a Core i7 anyway, in realistic scenarios.

As for VR, the difference is negligible as the games just aren't that CPU-intensive. The GPU matters a whole lot more.

That's why I recommend getting a cheaper CPU and spending the money on the GPU instead.
