Laptop for School

Well, I'm more than half way through summer and it is time to start thinking about school...I'll be studying architecture specifically this year and will require a laptop. The recommended specs for this year are not available yet (as usually our faculty is last when it comes to being up to date). Last year's specs were ... 2 GB RAM, 2.16 GHz Core 2 Processor, 100 GB Hard Drive and a discrete video graphics card. I would like my laptop to have at least a 2.4 GHz Core 2 Processor, 200 GB Hard Drive, and no less than 2 GB of RAM (I can always go to 4 GB when Best Buy or Future Shop has their 2GB modules for $40)....I'm budgeting no more than $3000 for everything (laptop + taxes + extended warranty), and that is not including the software as well. I need to get Adobe CS3, I'm thinking premium for $399 and AutoCAD for $199. I already have MS Office, I got the Ultimate Steal for $69.
