so most 1000 laptops will have the same quality parts. Laptops are made with components from multiple vendors pieced into one laptop.

But things you should consider:
The more powerfull the app (gaming and video especially) the more power needed to run equals less battery life.
Since you like to have many tabs get as much memory as possible that helps for multitasking.
The better you treat the laptop the longer it will last do preventative maintenance Air can the vents.

The best deals are on models being discontinued but you also get the less support.
