I agree that its probably best to get a 4k g-sync monitor, thanks.
I think I will have to go and see both monitors resolutions myself, just to be sure.
I do wish there was an ultra wide 4k g-sync monitor though haha.
One other thing I would like to ask, is if I were to upgrade my PC in the future, to support 2 or more gpu's, would a 4k 60hz monitor basically be useless, as my system at that stage, would most likely be able to produce over 60fps at 4k?
