Which budget laptop should i buy?

I'm looking for a laptop that is $450 and under which is my budget, & im planing to only use it for web browsing, chatting, photoshop, itunes, video editing & maybe streaming and some gaming that can be run on low or mid setting. But i highly doubt i am gonna be gaming on this laptop since i already have a gaming desktop for that. I'm more of an Asus fan and i've only been looking laptops from that brand but i dont know much about pcs which im still learning and if you give me something better please tell me.
