What's your budget?

What expectation of settings do you have?
What Oussebon said. Thats a big question to ask without any other info but to just throw an answer at you. youre going to want a beefier more expensive card to push out more frames, especially at a resolution of 4k. probably an RTX or AMD 5000 series.
