Or

Acer XB270H Abprz 27-inch Display Full HD NVIDIA G-SYNC (1920 x 1080) Widescreen Monitor

? Im going to game on one of them so which is the better choice. I have dual gtx 980 ti's and want the best experience
I was thinking aboit this monitor as well

Acer XB280HK bprz 28-inch Display Ultra HD 4K2K NVIDIA G-SYNC (3840 x 2160) Widescreen Monitor

But not entirely sure even 2 gtx 980 ti's can handle 4k from recent games and all.
