Need help with new monitor

I am currently using a 27" Benq VA, 24"LG and 23" Acer Touch but im wanting to make the leap to a QHD aka 1440p panel. I am realy leaning towards the x-star matte. Im a little scared of gaming with it being 8ms. Which do you think is a better panel and why? I really prefer the samsung pls over the LG IPS

You shouldn't be able to notice the 8ms response time I mean come on its 0.008 seconds, so if the monitor is under 125 hz there shouldn't be any way of detecting the response time. And it is said that the human eye can't notice more than 30hz anyways.
