Hi so I was going to get a Xbox one x but decoded to get my first PC instead which i get delivered next week I went for a i5 7400 and nvidia gtx 1060 6gb and 8gb of ddr4 will I be able to play on 4k at playable framerates
Probably. My RX 480 can do 30fps+ on a lot of games at ultra settings at 4k. I don't play at 4k, I play at 1080p so I can do ultra settings and 60+fps, but if my RX 480 can do it, I don't see why a GTX 1060 couldn't do "playable" framerates at 4k, depending on your definition of "playable", especially if you don't mind turning down a setting or two.
Why 4K? Just go 1080p.... What you'd be lacking is refresh rates, and it will seriously give you a headache after long periods of time if you do 4K (4K isn't even actually really a thing yet... I have 2 gtx 1080Ti and there are only a few triple A games that can keep up at above 60fps constant
