Agreed. Wonder what they'll suggest? Prob one with tons of fast memory. I read that most devs are using the new Nvidia 980s because the latency is less.
Then again, if you already have a decent GPU you can still do quite a bit. When I got my DK2 it ran many things just fine on an older GPU. I only upgraded to a GTX980 because I hadn't splurged on anything in a while and it helped a lot with un-optimized, demanding programs like Elite: Dangerous. I could have kept using my existing card if I just wanted to mess with less demanding content or make stuff in UE4.
Don't make it sound like Oculus is more expensive than what gamer already have to pay to get the best experience.
That being said, I'm sure you could play games on the lowest setting without the need for $1000 worth of GPU.
Pick any Mid-Range Card and upgrade once you hit a roadblock, that will keep your expenses reasonable while not excluding you from experiences if you deem them necessary.
Of course if you want to experience GTA 5 in this resolution and necessary framerate, thats a whole different matter.
The new PASCAL Nvidia cards will be out and so will the new Intel chips will be releasing this August (with potentially a progression to 7nm next year).
Honestly, I'm impressed you've been able to do a whole lot with it at all. I've got a fairly decent laptop (i7, 16GB RAM, and a mediocre nVidia 760m GPU) and it's still been underwhelming when I hooked the Rift up to it.
Desktop will be much more power for the buck this early in the game. Portable will catch up but you sacrifice some bang for the buck when you get something more optimized for portability and battery life.
