I'm headed to college this fall and I'm stuck in a dilemma between the following Macbook configs: 2.0GHz + 4GB RAM vs. 2.4GHz + 2GB RAM vs. 2.4 GHz + 4GB RAM I'm going to be an architecture major so I'll probably be using Photoshop and other such programs relatively often. However, I did speak to the department and they said that most of the heavy CAD/3D stuff isn't done until 3rd year - by which time I might go for some sort of upgrade? So apart from Photoshop I'll just be doing normal school stuff - Word, email, listening to music and watching movies. I'm not sure how much of a factor this plays, but I also plan on running Windows (hopefully I can get a hold of an XP disc) to run a couple programs. I considered getting the Pro but my parents don't want to spend that much cash on a laptop just yet. I'm leaning more towards the 2.4 GHz + 2GB or the 2.0 GHz + 4GB (the 2.4 + 4GB is kind of pushing my budget to the very limit) - which one would give me more bang for my buck? Any advice and recommendations would be great! What would you do if you were me?
