so finally LOL is finally on Mac, so i don't need to install windows anymore. but should i use the hd4000 or gt 650m when i play. When i play games i like to set video settings to almost the lowest. because for some reason high definition setting kinda makes it harder for me to see. so hd4000 or gt 650m all play well on my settings. but im assuming i should use 650m to play because it would be less stressful on the hardware vs using hd4000 to work the same task. what do you guys think? and i always have it plugged in when i play. so battery life isn't my concern.
