So i have been lurking around these forums for the past few months, but finally realized that i didn't have an account tonight. haha. anyway. I start at SFSU in less than a month, and am looking into getting either a MB or MBP. Problem is, i have heard this and that about performance equity between the high end MB and the low end MBP. I'm a biochemistry student, so i could potentially be running some semi heavy programs on my machine. I've been told by one apple rep to go for a MBP for the [slightly] faster processor and the video card, but another rep said i would be fine with a high-end MB after revealing my major. so i desire input from you guys. help? ps: the middle and high-end MBP aren't options due to financial constraints.
