and what i would like to do is be able to play games on it, more specifically: Starcraft II, Call of Duty: Modern Warfare II and eventually Modern Warfare III and if possible, put my playstation 2 emulator on it.
battery life isn't an issue for me as everywhere i intend to use this laptop will have an outlet (school, home, work)
Computer Games on Laptop Graphic Cards
AMD Radeon HD 6470M or NVIDIA GeForce GT 520M would mostly meet your goals.
AMD Radeon HD 6630M / Radeon HD 5650 or NVIDIA GeForce GT 525M / GeForce GT 425M, or better are where I think you want to start looking for a laptop gaming graphics card.
