Thief

Thief is a series of stealth video games in which the player takes the role of Garrett, a master thief in a fantasy/steampunk world resembling a cross between the Late Middle Ages and the Victorian era, with more advanced technologies interspersed. The series consists of Thief: The Dark Project (1998), Thief II: The Metal Age (2000), Thief: Deadly Shadows (2004) and Thief (2014). The main tactic of Thief is to avoid fights and instead sneak around the enemies. Thief is sometimes described as either a “first-person sneaker”, “sneak-em-up” or a “first-person looter” to emphasize this difference. Wikipedia

With 70 FPS at 1080p, the GTX 970 can run Thief at 1080p with no issues at all. Once turned up to 4K resolution the FPS dips down the to lower 30s, but fortunately it at least stays consistent so it is playable if 30FPS isn’t an issue to you.
