what are the PC specs?
I agree to all posts here. I am also hooked to VR. All I can contribute is that I believe a 1080GTX is minmum for VR.
OP just make sure you put some cash aside for a powerful GPU as ED in VR needs a lot of grunt to maintain close to 90 FPS with graphics settings turned up. I don't know what others think but I'd consider a 1080 to be the minimum (and remember 1080ti coming out in a matter of days).
It'll be a i7-7700K with Zotac 1080 Amp Extreme and 16GB of RAM.
It's not decided yet, but I think 1080Ti will be too expensive to put it into equation (rumors say at least £700, and Zotac's Amp Extreme will cost me £510, not sure that Ti justifies the cost).
