Clearly that is not true... if it were, we wouldn't have 144Hz monitors across the board, with 21:9 at 100Hz and both it and 4K already promising more soon. The future is NOT 60FPS lol! The difference between 60FPS and 100+ IS noticeable, perhaps not to you, but for the majority very much so (game dependent to some extent also though). Higher FPS will ALWAYS trump resolution (in vast majority of games anyway), that's just fact, and it's exactly what we SHOULD be chasing, far more so than resolution.4k at 60 fps is where the immediate future of gaming lies and I'm saving up for it as we speak.
What does it take to run 4k at 60fps?
ENTIRELY depends what games. The 1080 is not a 4K card, no matter what anyone tells you. It will handle some well, others not, with G-Sync being absolutely essential. It scrapes through, and it won't be long before this becomes worse. Unless you think a GPU becomes MORE powerful and games EASIER to drive the longer you own it lol?!
