So i have a 2 1/2 yr old Alienware Laptop. Used it for general school, gaming (league, dishonored, AC3-4, etc) as well as some pretty extensive 3-d modeling (engineering major). Lately ive noticed that although my laptop is fine for general use, i need something better/stronger. So Im wondering how can i build a computer speciffically for intense modeling and gaming? Does anyone know a good way to get started? Also anything recommended graphic, CPU, ram, and or memory i should take note of?
