None of those will run Oblivion or Fallout 3 worth a shit and anyone who says different is...well, full of shit.  You will need a good videocard in the laptop to run those games and a good CPU and 2 GB of ram.  GeForce 8800 series or better, Radeon HD 3800 series or higher, GeForce 9600 series or higher.  I hate to be the bearer of bad news but playing those games at any respectable settings is simply out of your price range.

 Sure it will boot it up and run but it's not gonna look good.  You might as well play Morrowind since it will probably look better than Oblivion on a laptop 9100 card.  You can't turn chicken shit into chicken salad and that is what you're trying to do if you go with these laptops.
