Filter my 4 (~$600) laptop choices for Diablo 3

[mls5stokes]

I have been looking to get a laptop that will handle the new Diablo 3 game about to be released. I am trying to keep it under $600.

I have been using notebookcheck with Mass Effect 3 as my bench mark (since D3 isn't available) to figure out which graphic cards to look at.

Requirements:
-Plays D3 on at least mid settings
-$600 before shipping/tax
-Gotta have a number pad built in (I <3 me some excel)

Here are the laptops that I have narrowed down in my search.

HP $600 (w/ upgrades) - AMD A6-3430MX; AMD Radeon HD 7690M ; 6GB RAM
HP $580 - AMD A8-3510MX; AMD Radeon HD 6750M; 8GB RAM
Acer $550 - i5-2450M; AMD Radeon HD 7670M; 4GB RAM
HP $530 - AMD A8-3500M; AMD Radeon HD 6750M; 6GB RAM

I have been doing this research for the past few days and now I'm wondering which one in combination with the processor/GPU/RAM will give me the best performance.

If I am missing anything please let me know what else to be looking for.
