I'm up for some opinions as I am finding it hard to make a decision. Current monitor Dell U2711. Current video solution 2 x R9-290's in CF Current game played: FPS- BF4, Metro, Tomb Raider, Arma lll. Looking to upgrade monitor but currently struggling to find a solution. Asus PB287Q looks good, 4K at 60hz. I like the extra real estate, and think that my video cards will be able to manage 60fps without FSAA enabled. Or 2560x1440 at 120hz??? Problem is that there is only one monitor that officially supports 120-144hz at 2560x1440 the ROG Swift and this comes with Gsync and is $800 (I don't need gsync and it's $180 more than the Asus 4K) Unofficially there are a bunch of Korean imports that can be overclocked and there is the Overlord Tempest that can also be overclocked to 120hz (tested to at least 96hz before it leaves factory)..... The problem with the Tempest and Korean imports is that there are a number of driver modifications that need to be performed to get these working and the overclocks are not guaranteed... I could do with some input from gamers that have tried 4k or an overclocked 1440 display, or preferably both... 4K at 60hz or 1440 at 96-120hz???
