I'm hoping to get a oculus rift soon but I was wanting to know if I might need to upgrade my gpu as well. My setup has a intel i5-4690k (stock clocks), 8gb rams, and a amd fury (stock clock). If I were to upgrade I plan to get a gtx 1070 at the most. I know it doesn't really out perform the fury to much but might it be worth it for vr?
