Tacos, I just wouldn't worry about it.
My expectation is that, there might be a few games that you can't run, but most of them would be no problem.
I can understand the recommendation.
Applications tend to be single threaded, and for VR applications, you'll want to be running pretty high frame rates. ~90+.
Not all games would need that kind of CPU to run at that frame rate, but I'm sure there are some that would.
