hi, i am attending Audio engineering in october and i am looking for a new Macbook that will replace my current core 2 duo unibody Macbook pro 15, which is still a nice machine but i want to sell it since it s still in warranty and i want something future-proof for like good 2 years that will run Logic smoothly with many plugins. I have been thinking about getting the previous gen 17 inch i5 model(which i could get for 1700 euros from the store who still has 2 or 3 in storage), or the new generation 15 inch sandy bridge, or the new 17 inch sandy bridge. I all ready bought an SSD which i will install in whichever model i choose. Have the problems with overheating with the new models been fixed? Would you recommend a 17 inch screen for audio? Are the differences between i5 previous gen. and the new processors huge or minor? I have heard that the 17 inch models have better screens, not just in resolution, but more color gamut, is this true? Sorry for any mistakes, english is not my first language Thank you for your answers.
