There's been a lot of speculation about what sort of system it will require to take advantage of the extensive graphics options in the upcoming Windows edition of Grand Theft Auto V. PC Gamer has word from Rockstar on this topic, reporting it won't take the beefiest computer to get to 60 frames-per-second at 1080p, but 4K resolution will be (and require) an entirely different beast:

According to Rockstar, the recommended specifications are based on hardware that can run the game at 1080p, at 60 frames-per-second. For that, Rockstar suggest a Nvidia GTX 660 2GB or AMD HD7870 2GB.

"To run the game on a 4K display at 30fps," says Hoare, "you’ll need at minimum an AMD HD 7870 or Nvidia GTX 760 with 2GB of VRAM." As for the 4K at 60 frames-per-second, that'll require a "high-end SLI or Crossfire setup."
