Firedani :
So I am planning buying an used Gtx 970 this summer. I have decided that I would rather buy an used gtx 970 than a new a GTX 1050 Ti since their price doesn't differ that much and the 970 should be much more powerful.
And my question is that my I3 4330 will be enough to run the game? Not planning on upgrading cpu ATM though.
Yes, the i3-4330 + GTX 970
can run Witcher III. Performance depends on you in-game settings and resolution. I can't find a sample gameplay with the same CPU + GPU, but, below is a game performance test using an i3-4170 + GTX 970 (w/ 16GB RAM) in High Detail (w/ Hairworks On). Note that the i3-4170 is
slightly better than the i3-4330 (http://cpu.userbenchmark.com/Compare/Intel-Core-i3-4330-vs-Intel-Core-i3-4170/2876vsm28214), so, you can just deduce on a more-or-less basis the fps you'll experience based on the video below:
