Buy a Dell,

but call them, don't order through the web, and blag some,

you can easy get 25% off if you're persistent.
You have good games spec PC's at dell, but they cost a bit

Just take one with 4 or 5 years warranty and you're laughing

Oh I like Dell better then HP, but they're both good,

just stay for away from packard bell, they use crap components.
