A:AnswerIt depends on your headset. This model doesn’t have display port so if you’re using Oculus Rift S then you’ll need some sort of adapter. The CPU and GPU are way above what oculus requires so it will be fine in that regard.
A:AnswerThe G14 and G15 both use AMD's new Ryzen 4000 CPU and have been reviewed/benchmarked to show really powerful CPU results. The G14 is in a smaller chassis, and the G15 has shown to have a bad thermal design. I think some reviewers have estimated that the G15 and M15 share screen options: dimmer 144Hz and this brighter 240Hz panel. And only thee M15 has thunderbolt 3.
