I'm sorry to say, but just because the system was built in 2015 and the CPU itself was released a year or two before that, doesn't make it good.
The CPU is built on the Bulldozer architecture, which runs on FM2+ which came out forever ago.
It doesn't mean anything when it comes to performance.
However, sure, let's say you are overclocking it as far as it can go with an aftermarket cooler.
And let's say it keeps up with the games you wanna play using VR headset.
Your GPU is still too low spec for a proper VR experience.
You'll need something with the performance of a GTX 1070 or better.
Furthermore, a 180w PSU is downright amazing to me that it's powering your system effectively.
I will have to assume that the 1050 Ti you have is PCIe power only and doesn't require external power cables.
Also, with a PSU like that, I have to retract my statement about overclocking the CPU. It simply just cannot be done with a PSU of that low spec.
