I bought a XPS 1530 Dell Laptop. It's Awsome because Dell is currently doing 0% Interest for 12 months on all XPS models. Plus its a 15' built for gaming and practical use too. I prefer 15' over 17' because its not as heavy (smaller battery) and easier to take while traveling. I am in the military and currently doing school too, so I got a discount. It has 3g of RAM, and a 8600 NVidia GT, its a 15' LCD HD Screen with an HDMI input/output built-in. It runs smooth, has a built in camera, finger print reader for security. I paid like $1100 for it, but is started at $999 (without discount) with 2g RAM and a 8500 NVidia, but I upgraded it.
They build it within 5 days and ship it to you via UPS/Fed-Ex. If you dont like Vista you could probably get it cheaper with XP. I used to bash Dell, until I got this laptop and MrMarc is right, Dell makes great laptops. Hope it helps but just hit their site, you can build it from the ground up, and save your builds for future look, its cool. Link provided.
