We'll have to see how fast VR/4K becomes 'standard'
Price has A LOT to do with it. When those systems get priced for the main stream (i.e. like 1080p now), that's when they will be widely adopted.
@OP: For your CPU, you are good for at least 2 to 3 years. My CPU is older than yours and I still don't feel or see a need to upgrade. My CPU doesn't hinder the performance in any noticeable way, but I might upgrade after Kaby Lake comes out. A strong GPU goes a long way in gaming.
