Your CPU will work well if you stick to VR with background tasks turned off. It can handle more workloads, but VR still has the worst performance in the lowest 1%. Keeping your system fresh is ideal. Your GPU, on the other hand, is a definite no—consider upgrading it before the CPU because you might gain a year or two of longevity from the CPU if you only run VR inside it.
4 cores and 4 threads work well for VR; single-threaded performance shines. Your processor matches an i7 4770K, which I previously ran with my HTC Vive, so you can expect solid results. I also tested a GTX 970, comparable to your RX 570, which performed nicely too.
The CPU should work adequately. A minimum of four cores is recommended for modern gaming, though other factors also play a role. Single-core speed is equally important.
