Need Advice Please

Hello,

I currently have two systems: a desktop for home and a crappy old laptop for work. The desktop is a P4 3.0GHz, 2GB RAM with ATI X1650. The laptop is some old Dell latitude that can barely run assemblies I work with in Pro/Engineer. However, I really only use the laptop to program servos and other equipment that don't really require a lot of computing power.

I am looking to get a laptop that can replace both my desktop and my laptop. Since I'm on a lot of business trips, it'd be nice to have a laptop that can run games as well as my desktop (well... hopefully better). I've been thinking of this especially because of the new games coming out soon: Bioshock and Enemy Territory: Quake Wars. Right now, Quake Wars is running pretty badly on my system. I have to bring my resolution down to 800x600, turn off anti-aliasing and put everything else on low (with no shadows) to maintain a constant 30fps.

I don't think my laptop can even run games. It can't even run WoW on low settings properly without incessant freezes.

So I really have no clue about laptops. This desktop is one I made myself which I kept upgrading to the point where I'm sure it's going to die pretty soon. I mean, I had to rig myself a new power switch since the original one is worn down.

Anyway, the only familiar brand I know is Dell. And looking at the Alienware website I could see some very nice gaming rigs and obviously expensive. I'm fairly sure they are overpriced since I could make some of their desktop options myself via Newegg for much cheaper. I'm interested in the dual SLI technology they got on their laptops. I know it doesn't work with Vista yet but I'm not too interested in upgrading to Vista yet anyway.

So please guys, help me out and point me in the right direction. It's been awhile since I ran a game at the settings in which it is intended to run at. I'm getting tired of looking for tweaks that will make the game look crappier but playable.

Thank you in advance,

Frank
