At 4k that card won't run many games well. If you will "ever need to replace it", that depends on what you play, and at what settings. It's like asking if a gallon of milk is OK for the week without any other info like for how many people, how much milk they like to use, etc... Maybe you live with 8 people that eat cereal 3 times a day, without info it's impossible to say.I don't know what games and apps yet. New to the scene. Just trying to get a feel if there many things this card cannot handle. I do have a new 4K monitor as well. And an EVGA 700W PSU.
