Well, I'd say you can but I wouldn't recommend it if you do not get the VR gear for free. While it is cool for few sessions VR is not that far yet and even with a high-end PC the fact that current major glasses still have quite low pixel densities makes your experience worse than what you might expect. It's still a cool gadget but IMHO you would have much more fun with some decent PC upgrades - especially for your CPU, which you might actually see in most games. So at the very least (maybe you already did) I'd test VR first, also so you can see whether you are sensitive to motion sickness.
