I am selling some old crap to get 2000 dollars this summer and am thinking of getting a hardcore prebuilt gaming laptop that kicks total 9999% ass, and can play games at max max max settings with no lag.
It is possible to build your own, by getting a MSI Whitebook (http/www.msiwhitebook.com/product_spec.asp?model=MS-1762) and getting the other parts via eBay. This method is much more challenging than buying a prebuilt, but it gives you better control than a prebuilt.
2000 dollars is a good budget to start with for a build. Would you like a desktop or laptop build?
He said laptop in the post...
Also, a gaming laptop isn't the best choice for gaming "maxed out". Gaming laptops are more for gaming at Mediumish settings with "goodish" FPS. They are mostly used by people that travel a lot and don't need max settings, or people in university who need a powerful laptop for graphic design and graphically intense work.
