Waste of money.
I'm a computer science major and I have a MacBook. A lot students have the MacBook Pro. I don't understand why all these incoming students feel the need to buy one in the economic climate that we are now, unless you have a large amount of cash to burn (in which case you do, give me some

)
But really, you should give it some thought... I paid:
(MacBook 4,1) 2.4GHz, 4GB, 500GB... $1400.00
The 9400m in the MacBook Alu will be more than fine to do light 3d-rendering and photoshop. Upgrade it to 4GB/500GB or so like myself and save a bundle.. if you do your research, you'll see what a better value it is.
If you still go for a pro, 17" is just blowing money. Go the entry level 15".
EDIT: Plus, if you get a regular MacBook, you won't have to worry about your video card ******** out on you in a couple years. I know for sure as hell that my X3100 isn't going to burn itself up and quit working as soon as my AppleCare runs out.
