If I have a 60hz minotor,can I see 60fps? Does 144Hz have any benifits? Should my Hz be greater or less than my games FPS?
That's the refresh rate, which would indeed be the maximum fps it can support. A 60hz monitor will display 60fps gameplay even if the game says you're running at 100+ fps.
144hz means you'll be able to see upwards of 144 fps on your screen. This will make movement seem more fluid (more frames per second). A lot of people recommend 144hz for FPS gamers for the fluidity, lack of choppiness, and reaction time. Do note that 144hz is harder for your GPU to achieve, of course.
