PC gamer said about GTA V
I was shown the game in 4K resolution running at 60fps. The PC Rockstar was demoing it on is outside the price range of most consumers, with an i7 5930k@3.50GHz, SLI GTX 980, 32GB of RAM and a 256GB SSD, but that’s just to show off how pretty it can look. Rockstar says that even average rigs won’t have a problem getting great 1080p performance out of the game, which is encouraging. Scalability is a priority for them.

"And after playing it on a truly monstrous PC – an i7 with 16 Gb RAM running dual GeForce 980s, driving a 4K monitor at 60 frames-per-second, I think they’ve got a point. "
“We wanted people with older or less powerful hardware to still be able to play V, rather than requiring the latest greatest hardware,” a team of senior staff from Rockstar North told us - director of technology Phil Hooker, director of engineering Klaas Schilstra and technical director Adam Fowler.
Machines at minimum spec are expected to handle GTA V at 800x600 and 20 to 30 frames-per-second - while recommended spec systems should manage 1080p and meet 60fps on medium settings.
Taking advantage of the 4K support will be a different matter: you’ll need an AMD HD 7870 or NVidia GTX 760 with 2GB of VRAM, at least, to reach 30fps - and a high-end SLI or Crossfire setup to top 60fps.
