What an epic game this turned out to be, best version of GTA5 I've played.
Runs fine on very high on my i7, 16gb, and 970GTX at 1080p.
I actually like the fact that I can't run it on ultra at 4k, gives me something to look forward to in future when I update hardware. This game is going to be played for a lot of years. I really think it's awesome that this game goes up to 11 so to speak.
Hardly had any issues with the game at all, in fact story mode thus far has played perfectly, I only had an issue with the editor mode when exporting large files it would crash but Rockstar have sorted that with their recent 200mb patch.
