what is the 940mx overclocked capable of?

HI guys and girl. Im getting a ux430uq with a 940mx and plan on overclocking it im getting the laptop for 530usd due to false advertising of their cheaper model. so im pretty happy to save 880cad.

if it overclocks 135 core and 200 mem..do you think ill be able to game on low at 1080p or will i be stuck with 720p gaming. also should i run at med/high at 720p or low 1080p which will look better. once again thank you for your help and also sorry for all the questions im just super excited
