100GB 5400rpm Serial ATA hard drive
Slot-load SuperDrive (DVD±RW/CD-RW)

1GHz Frontside bus
1mb L2 cache per core
160GB HD

I was thinking to things

Wait until Parents buy Mac (would be soon) and get nice one and i just upgrade Laptop.

Or Upgrade Laptop for portiblity for school and save for desktop later.

Last Buy desktop, keep laptop for school for smaller projects, then buy Macbook since its alot faster.

What should i do? I need a computer that will be fast for Video and pictures i would do probaly 80% of it at home 20% of laptop at school.

So i was thinking desktop then upgrade Laptop to Macbook.

Sounds like you've answered your own question.
I think your thought process seems solid. if you're going to use the desktop more often... then that seems like the logical computer to replace first.
