Getting started

[Da Splatter Man]

I've been a hardcore gamer since I was 12 (currently 16 in 10th grade) and chose maybe in 8th I want to make videogames. I really have no idea what kind of classes to take for it so I'm in a photoshop class and a 3D imaging class! I want to go to Full Sail when I graduate cause its actually pretty close to home. I know I need to start using software but our computer sucks and I don't have a job to get a new one? Wats the best laptop for this kinda stuff or do I need a big computer? And what's good software? I know Unity.
