Question I'm playing FPS and racing games - what features do I need in a monitor?

[swapjim]

I'm playing first-person shooters and racing games at 85 fps (anything above doesn't make a difference to my eye). What characteristics should I seek in a monitor?

Do the 85fps translate to 85Hz, and anything above is redundancy? Should I seek 1ms response time?

I have an AMD supporting FreeSync so a FreeSync monitor will improve things further?
