Why haven't you joined the PC master race yet, Yea Forums?

I did like five years ago. I'm planning on upgrading my rig in like two or three years. I don't really have many opportunities to use it anymore.

How long do you think a gtx 1060 6gb graphics card will last me?
Keep in mind I play in 1080p and don't mind going down from ultra to high or even medium.

What is gaming like on linux?

Hmm tough question, if 60 fps is your goal and you don't mind going down to medium, you probably have a few years left in that card.
