The best 4K graphics cards usually cost about £700-£1,700. This is a premium part of the graphics-card market, because modern 4K gaming needs much more GPU headroom than 1080p or lighter 1440p play. Very cheap cards do exist, but they are not where a serious 4K buying decision starts.
Below roughly £690, 4K usually means heavier compromise, older hardware, or limited long-term headroom. Around £700-£1,300, you start to see much stronger cards that can handle 4K more comfortably in modern games. Around £1,300-£1,700, the focus shifts to faster high-end models with more headroom for ray tracing and tougher settings. Above that, you are mostly paying for flagship territory rather than for a normal 4K upgrade.
