getting into a design course and i'm looking to get a mac (my first

) before it starts.
would a macbook be enough for photoshop, video editting and a fair bit of 3D work? as it stands, my parents are willing to cover the cost for the high end macbook with a few upgrades. i've got enough to add to that to get the mid end 15" though.
is the extra punch of the mbp worth the extra $600-$700 though? or is an upgraded macbook enough to last me until the end of my uni years?
OK, well I am currently working part time as a webs designer and graphic designer. I have the tip top of the range MacBook (Black book- 2ghz, 2gb ram etc)...
I use sketchup, vectorworks, form z (heavy stuff), iMovie, Aperture, and all the cs3 suite.
I have TWO problems with my current setup:
1: screen size, Just 13", 15" is no good - really I want 23" and you can't get that on a laptop. Solution? get an external screen.
2: When I try to open up say 5 or more massive multi MB Tiff or RAW images all at once in photoshop whilst Aperture is still open - it really suffers. Solution? Shut Aperture when you're opening photoshop, and only have 2 or 3 of those enormous photos open at once.
Basically, My setup is liveable with and I use it 8 hours a day for my main job and for my freelance photography work.
What I suggest to you is that you get the tip top MacBook (not pro), and spend the extra money on a screen. I promise that you will not regret.
The only thing I will tell you is that if you're really really picky, you may find the build quality of the MacBook less satisfying than the MacBookPro, which is beautiful. I have mine covered in a speck see through plastic cover which absorbs all the little bumps and stops the plastic coating getting scratched. The glossy screen isn't to my liking, but is liveable with especially if you have a nice external screen to look at instead.
p.s I've been saving up for a MacPro because you can't install Final Cut on a MacBook.
