What Macbook Pro should I get for college?

Honestly, from what you described it doesn't appear like you will be running many applications at once (not more than two or three) and you don't have any processor/RAM intensive applications that you'll be using (except maybe photoshop). Honestly, 4 GB of RAM should be plenty. I mean if you add more you'll start to see if a difference if you get to a point when you are using up close to the whole 4 GB, but if you are just going to play a few games, browse, the web, and type in word, 4 will give you more than enough. I have the same feelings on i5 to i7. You may see a difference, but not a HUGE difference in what you are doing. However, you said you were a casual gamer so if you play games often that are very graphic intensive and the performance while you play is very important to you, you may want to think of adding just a little more RAM (maybe not a full 8 GB) and you may also want to spring for the i7.

I'd recommend the cheapest Macbook Pro 13" (the one with the i5 and 4 GB of RAM). i'm also a student and I've get this mac a week ago and I love it. For your needs you won't be dissapointed with this model.

Talking about gaming, I've played yesterday Counter-Strike Source and the performance isn't bad. You won't get awesome textures and that kind of things, but for a casual gamer you'll fine with this model, along with the others things such as browsing, Mail, Chat, Office, etc.

Remember, you can always upgrade the ram. I would go for the 7200 RPM drive if offered.

It's what I got in my 2011 MBP, I can't hear it, and it runs cool. Battery run time seems on par with what is touted. 7200 vs 5400 in my other notebooks made a big different in speed.

I put a Hybrid Seagate drive in my Dell Latitide months ago. That thing flies. Thinking about putting one in the MBP.

I have the Seagate Hybrid in my Dell.
