I am looking into purchasing a MBP but did not know if I should get the 13" with the integrated graphics or go with the 15" with the dedicated graphics. I am going to use the MBP mainly to edit videos and pictures in Aperture and Final Cut Express, but nothing very heavy. I am leaning towards the 13" due to the cost factor but would hate to waste my money on it if it will be running at maximum potential just to perform simple tasks that the 15" would hardly break a sweat on. In case this will help with anybody's comments, I will be increasing the RAM to 8gb either way. Help.
