Hi, i am looking at monitor or projector upgrade used for only pc sim car racing. i am currently running a 1080 60hz projector with gtx970 with no tearing or issues. Runs quite smoothly but wondering if i will really notice the jump from 60 -120hz???
here is the 3 options I'm looking at:

1. benq w1080st+ projector 1080 60hz

2. either 1 x benq xr3501 1080 144hz http://www.benq.com.au/product/monitor/xr3501/

1 x Acer predator z35 1080 144 hz monitor http://us.acer.com/ac/en/US/content/predator-z35-series

Many thanks for any replies.
