Looking for a gaming laptop

[AMKANMBA]

I'm looking for a gaming laptop which is suitable for my needs. I travel alot so battery life is a big factor. I personally think that a gaming laptop with a gaming/graphics dock or amplifier would be ideal for me.
So to sum it up, the perfect thing for me would be:
1) graphics dock
2) 17.3" screen (or whatever's bigger than15")
3) a decent amount of battery life
