I'd wait. You're in a goos position in thatr you have a device which doesn't require your PC anyway to have fun with.
I wouldn't upgrade GPU just for VR.
Yeah, that's kind of my thinking really. I mostly game on console these days or in VR however, as much as I enjoy it, I don't really want to spend ~£400 on my PC purely for VR gaming. I've had to drop the detail levels to low in some of the more demanding tites (like Asgards Wrath) but I can still at least play all the games so far.
I know there's always something better, faster and cheaper on the horizon in the world of technology but looking at what's coming up in the next year it feels like waiting makes sense. More than ever now I'd like to abandon my gaming PC and more to a laptop and console based setup.
Specfically, I'm wondering whether there will be any Playstation VR announcements this year alongside the Playstation 5 release?
