Why would it need a GTX970? Surely it'd be based on the game you're playing? Was going to get a Micro-ATX with a GTX950... Not sure I want to pay an extra £150 for a GTX970... Ugh, decisions
The 970 is the recommendation because of the FPS you gotta hit at the 2 screen resolution. My 770 hits 60 FPS @ 1080 with basically any newer game, but only 144 FPS (I got a gsync monitor) in older games like DOOM 3 or WoW in lower complexity. 60fps at 1080 is probably magnitudes easier to hit than 2160x1200 @ 90 FPS
They said you need a geekbench benchmark of over 9000! (heh meme, but seriously) to get the optimal experience in most VR games. Since that score represents like 1% of the PC market right now, I bet many will be trying to get by with less. I am glad it's not like nvidia where they would not offer some of their features unless you hit a certain spec. Game stream isn't an option unless you have an specific i3 2100 or better regardless of the GPU being Kepler class or not which I thought was bullshit.
There is a line where shitty experience should at least be allowed to be attempted. Oculus allowing that experience seems better, and the recommendations seem as just that rather than actual "minimum requirements"
Plus, directx 12 compliant, Why not get a 970? That's gonna be my justification to myself hehe. Although I am a bit torn on waiting on pascal.
