Lappy

I'm looking for laptops; which would you choose?

A better GPU with a lower res (Radeon HD4650 @ 1366x768; 16")?

OR

A worse GPU at a higher resolution (Radeon HD4570 @ 1600x900, 15.5")?

Laptop will be general purpose--college, movies, some gaming perhaps.

Thanks in advance.

high res is infinitely more useful.
