The 1920x1080 is about 80 pounds more expensive. I just want to play some games on it (max payne 3, far cry 3...) will the 1366 x 768 make it any worse ? The gpu is gtx 850m.
Less pixels will make it less sharp. You will however get higher frame rates on the 1366x768 res making game play smoother. With a GT 850m I'd say 1366x768 res is fine.
if the laptop with 1080 p had the same gpu as laptop with 720p then yes the 720p would be better ...increase in resolution means decrease in fps so stronger gpu....
