If this for a PC setup which I would assume it is I would go with monitor since it is better for PC and less response time from 1ms to 2ms on most new 4k monitors like the Asus. Your graphics card should definitely be able to handle a 4k monitor. But i don't think you will be able to buy 3 4k monitors for the price of 800 - 900. For a 4k tv definitely but it wouldn't be the best 4k tv.
