hi thanks for your reply , my cpu is a 4790 haswell and my mobo is a z97-k . so you say the blue usb 3.0 is enough ? and the red 3.1 not needed ? can i add 3.1 with the pic e 1x slots ??
so if you were me would you buy occulos rift now or save up for htc vive later ? i say cause i just checked doom VFR and it says htc vive nothing about occulos ?! what other stuff vive's got that occulas does not ? do you have yo use a gamepad or a steam controller instead ?! you certainly don't need to use the mouse and keyboard ?
can i play my current 2016 doom with occulos ? what other cool games there bro ? multiplayer too ?!
thanks for the info
Your CPU and motherboard should be fine for VR. You won't need a PCIe card to add USB ports, unless you have a LOT of other stuff plugged in. Personally I'm using an older Core i5-3450 and Z75 motherboard, and it's doing fine.
I would either go for an Oculus Rift now, or wait for new headsets; the Vive is simply not worth it at all. There is a new SteamVR headset in development from LG, like a new Vive, but it's not going to be a full generation ahead, more like a minor update. Truly next-gen VR headsets aren't expected until 2019 or maybe in time for Christmas in 2018.
Doom VFR uses SteamVR, and thus it will work on the Oculus Rift. The reason they don't advertise it is that Zenimax are in a lawsuit against Oculus/Facebook. Doom VFR is a reworked version of Doom (2016), which otherwise isn't made for VR (again, you could "hack" VR support with VorpX, but I don't think it would be a good experience like that).
Since the Vive uses SteamVR, which explicitly supports the Rift as well, all games that run on a Vive will also run on an Oculus Rift.
VR games either use the motion controllers that come with the headset, or a traditional gamepad. Keyboard and mouse is rarely used for VR, it's pretty awkward.
There are lots of other good games. Arizona Sunshine for solo or co-op zombie shooting, Onward or Pavlov are multiplayer shooters, and then there's Robo Recall, Superhot VR, Thumper, The Climb, Star Trek Bridge Crew... even simple things like Eleven Table Tennis (just a table tennis game, but it's fun).
