7nm Nvidia cards should be coming next year. Nvidia needs to do it next year as they're currently losing on profit margins. AMD just released their 7nm cards, so I guess their next gen card will come after Nvidia's. Hitting 1080p 60fps shouldn't be a problem in newer titles. I reckon it won't be any different in upcoming titles (games barely get more taxing since 5 years ago, so I assume it'll be the same). The will become CPU more and more of a factor in the future at that resolution, though. But I'd say a 4C/8T i7 would do just fine for 60 Hz gaming.
