Intel - king of low-res gaming
Resolution is a smaller factor for the cpu as you migth think. I'd switch to 1440p 120+hz if there where
videocards that can handle it....
until then you better stick with 1080p.
Everyone is super hyped about resolutions but most people couldnt even tell the difference between 2k and 4k if they are not sitting 15inch in front of a 32inch monitor.
Most people love adaptive-/fre-sync because everythign looks smooth. But what if i told you its the the technologie its just the higher visible framerate that is looking great. your card only had to be capable of 60fps on a 60hz monitor wouldnt make much sense to try to gain any more.
If you monitor can only show 60 different frames a second, why would you bother trying to get the card and cpu to calculate more?.
I got a 4K monitor for work but would never game on it as i cant stand the sloppy movement of 60hhz monitors anymore.
sadly there is no way of experienceing more than 60fps on a 60hz monitor so you can only physically test it out.
