portable laptops can never be gaming PC.
what's portable?
small laptops that can be easily put onto trail table.
hand hold device that can be easily carried around and have at least 5 hours of battery life.
what's a gaming PC?
a PC that can handle all game you throw at it
a PC that can provide constant performance, not 2/3 performance when on battery mode
so you see, there is no such thing as gaming laptops, all you going to get is a half way house where it's neither really a laptop (in sense that it sucks at battery life and weights a ton) and isn't really a gaming PC (in a sense that it won't perform and doesn't allow easy upgrade of graphics card)
best solution for university students is like what i've done: a beast of a gaming PC, and an iPhone for portable entertainment. (or Asus EEE, MSI Wind, etc)
PC's go outdated very fast, so just sell the uni. PC when moving away.
