I'm a student from Norway and I'm considering about buying a MBP im often using PS3 and gaming 3d games, so I was wondering about MBP 2.6GHz 4GB SR led would be good for me? I'll also be using it for school, so battery life time is important aswell as silentness. I have been seen people saying that led screen is bad, that it often has bugs and so on, etc discolouring at some spots. On some other forums i've been told to buy with 2gb only, and upgrade it somewhere else instead of apple, because they have so expensive ram. Could someone with experience tell me about i should upgrade it from apple or somewhere else?
