How exactly can you tell that the VRMs are bad though?
It has a 4+1 power phase design, which is okay, but not great for overclocking, especially on chips like the FX-8320 which takes up to 125W at stock. It's bad in that it limits overclocking potential. But if you don't plan to overclock, don't worry about it.

Also, will the motherboard having bad VRMs make it throttle the CPU down?
No. It limits overclocking potential.
