Couple of hours in, after the forced prologue I took the blimp to Chilliad. It is a beautiful game, with lots of foliage. I like the touchpad to change radio stations and the lightbar flashes when theres police after you.
I switched to first person for the first time. I got excited when i saw a cat, I tried to punch it and Franklin just stomped the cat to death.
The online character creator is cool, you can modify your existing guy.
Assuming the game is not too demanding on the CPU, my current setup (well, once the 970 arrives, anyways) should be sufficient to run the game at high settings...though this is based on assumptions made on what the latest games require to run smoothly. My biggest concern right now is my non-K i7-3770. In theory it should be enough, but I could be completely wrong...
