How will?
It will take some time to get GTA V running smoothly on your PC. Your system specs look solid but may need optimization for the best performance. The game should run at 1080p with maximum settings, but keep an eye on frame rates and load times. Updating drivers and ensuring all components are compatible can help.
No one is certain about the expectations, and likely not clearly defined.
However, the system requirements for it are already met. (This isn't official, but it likely reflects the actual PC needs)
They claimed it required an i5 and a GTX 770, but that wasn't necessary for you.
It relies on optimization quality. GTA IV wasn't well optimized then, so improvements likely won't be significant. It might end up as a sluggish port.
