What's the budget?
Personally I'd be getting any i7, as much RAM as you can (16GB should really be fine tbh, but it's cheap enough so 32GB is always a nice to have), and then the fastest Nvidia card you can get your hands on. A 1070 would be my absolute minimum, preferably a 1080 if budget allows as that will be a noticeable step up if you're aiming at VR. My current 980 will do something like Doom at 1080/60 on Ultra with the occasional drop to 50fps, but that's a year old now and you want to be looking forward. Vive uses 2160x1200, so significantly more and you can expect the Vive 2 to be higher than that again (hopefully closer to 1920x1080 in each eye), so you really want the best you can here.
I prefer Intel SSDs, and my current setup has one SSD for the OS and generic programs like PS, iTunes etc. Another SSD takes the popular games where loading can be a pain (Skyrim, Fallout 4 etc), then I have two regular SATA drives for everything else.
