I'm ordering Apple's new Macbook and I'm wondering how much RAM i should invest in. Should I stay with 2 sticks of 1GB DDR3 (2GB) or upgrade to 2 sticks of 2GB DDR3 (4GB)? I expect it to run a program like Photoshop or run a downloaded movie while surfing the internet without lag. It wont be commonplace, but when I do fire up a graphics intensive game, like CS or WoW, I expect it to run at an above average FPS rate. Any suggestions or advice on how much RAM I should order? Thanks in advance.
