Question about Samsung LU28R550UQRXEN

Hello Community I have been toying with a new monitor for a while. I need the monitor primarily for office work with my Macbook Pro, but from time to time I would also like to gamble on it, without great demands on FPS, details, etc.. I have a PC with a GTX970. I don't want to invest in new hardware at the moment. Do you think it can drive the monitor reasonably well, or is it hopelessly overtaxed? Basically I'd rather have a UHD monitor than a 1440p, but if the 970 can't handle it at all, maybe a 1440p would be better? Thanks for the advice :)
