Frankly, unless you need to use a computer in a lot of places, don't buy a laptop.
Especially, when you're only on a 800 dollar budget.
Common knowledge here in Taiwan:
Laptop parts cost around twice the price of desktops.
Laptops overheat when playing games, at least the games that require good 3d image processing. (try running a good racing game on it for a few hours and see how well it does. ie:NFS series)
Laptops are hard to upgrade.
Laptop parts are prone to 'break' easily due to constant vibration ( whenever you move the laptop it somewhat vibrates everything inside, no matter how 'good' the anti-shock technology it has is)
For 800 bucks I can get a desktop with a high end VGA card that can handle 99% of the games in the market.
For 800 bucks I could get a laptop that can play some of the low requirement games and handle 'secretary' usage.
Think carefully about your needs and your budget. You can normally get the same setup for a desktop at half the price of a laptop.
