Thanks for the quick answer! But if im gaming, can I lower my resolution to 1366x768 if I have a 1920x1080 screen? What if I'n not gaming? Will the graphics look bad if its not a 1080 screen?
I used to have a dell studio 15" laptop and always lowered the screen resolution to 1650x1050 just to be able to read all the texts. 1920x1080p is an overkill for that screen size even if your not gaming. My 13" mbp looks super sharp with 1280x800 resolution. For gaming, the gtx660m will be better provided the rest of the system specs of those laptops are same/similar. 1366x768 is sharp enough for a 15" screen.
