I wouldn't say laptops suck HK
. While not ideally designed for gaming they can get the job done if its good enough. Speaking from experience it will work nicely depending on the game of course.
And Jay it depends on YOUR needs, as HK pointed out a general rule is to stick to desktops for gaming if you have a choice. You can even upgrade that machine as I agree with HK on it being a weak dedicated GPU.
And since you just say gaming let us know what games you plan on playing. As not all games are the same like on a console. Especially if you plan on playing something like Battlefield Bad Company 2, as neither machine is really gonna cut it.
Edit: I looked up that laptop GPU and found this interesting benchmark if you haven't seen it before.
LINK - It looks better then I thought but still only playable on low and probably not benched during the most extreme game-play.
