What are the two most important things for first-person shooters (also commonly known as FPS games)? Great gameplay and immersive environments. Though the former is entirely the domain of the game design team, hot-blooded gamers want, nay, need the latest and most powerful hardware. After all, how else can we run the newest gaming titles with mind-numbing frames per second at near-impossible resolutions?

However, immersive graphics comes at a price. For the hardcore gamers, only dual-GPU laptops like the Asus G70 and Alienware M17x will do. Alienware might not ring a bell for non-gamers, those in the know will recognize the brand as being in the forefront of portable gaming laptops in the US for years. Though Dell bought over the Alienware team in 2006, it was only this year that the distinctive alien head logo started appearing in Asia. However, dual-GPU machines are not cheap so for those on a smaller budget, powerful single-GPU notebooks are good alternatives which can handle almost any game but at a more modest frame rate.
