I'm buying a computer for my new school (ive been using the crappy 2006 macbook white with a intel GMA 950 chip -.-). I saw the 2 options (unless i want to get a macbook air ). Macbook pro 13" Intel Dual-core 2.3 Ghz i5 / 4 gb/ 320 gb hdd/ intel hd graphics 3000/ vs Macbook pro 15" Intel quad-core 2.0 ghz i7/ 4gb/ 500 g/ AMD Radeon HD 6490M with 256mb GDDR5. The 2 things I'm wondering is firstly, Intel quad-core 2.0 ghz i7 vs Intel Dual-core 2.3 Ghz i5 for gaming and using imovie and photoshops etc. intel hd graphics 3000 vs AMD Radeon HD 6490M with 256mb GDDR5 which one is better for AMD Radeon HD 6490M with 256mb GDDR5? Please help me I'm curious which one is better and its still alot of money so I want to get the best thanks in advance.
