ok yung cellphone vr headsets, OLED quality kung OLED phone mo, pero you definitely need a wireless controller for pausing videos among other things.
wala akong experience sa vr headset for PCs, but from what I know you definitely need discrete gpu for it, as opposed to just on-board video
kung ang goal mo on this pc is for watching porn on your browser as in the og post, definitely don't bother with a discrete gpu, ok na yung on-board video, instead add more budget to ram kase google chrome hahaha.
kung ang goal mo ay to play vr adult games you'll need a pretty beefy discrete gpu.
kung vr porn, I definitely recommend cellphone vr headsets, kaso kailangan mo munang maghanap ng wireless controller na gagana sa phone mo.
anyways do your research, di ako knowledgeable sa VR headsets themselves. Good Luck!
