Note that VorpX does not come with any games, but is a way to play your non-VR games in the Rift or Vive. It requires a one-time payment of about $40, and of course, it requires ownership of the games you'd like to play. Casual VR gamer? VorpX is definitely worth a try even if you revert back to your monitor for marathon gaming sessions. The answer, then, is really based on you as a gamer. The current build of VorpX is a much smoother experience, and the built-in optimizer does a far better job of tweaking settings to make a 2D game seem like a 3D game. There was a bit of dizziness due to the discord between eyes and ears, but it seemed to abate as I played. When I first tested an early build of VorpX a couple of years ago, it was a much heavier experience. Playing games in the first-person view with VorpX takes a bit of getting used to. If you're into competitive gaming that requires reactions measured in milliseconds, you'll want to stick with a monitor that has high a refresh rate and a high response time. Then again, playing DOOM on a monitor when you have a heart condition might not be a great idea, either. If you have a heart condition, playing DOOM at full volume with a VR headset on might not be the best idea. The answer to this question depends on what type of gamer you are.
