Left4Dead GTX-280 SLI vs 4870 1GB Crossfire @ Bjorn3D
 

Left 4 Dead, a revival of the FPS Horror Genre, was released on November 18th 2008, published by Valve and much to our surprise, was a DX9 game. The single player game consists of four levels where you're trying to reach a destination and get rescued. Each of the four levels has its own rescue point. While making your way to the rescue points you'll encounter hordes of Zombies, the occasional Boomer, solitary Hunters, occasional Zombie Witches, choking Smokers, and the dreaded Tank. Each has its own strategy, and their AI allows them to attack in different ways. While Zombie AI is what you'd expect from the recently dead returned to life, Boomers and Hunters have a more refined AI that allows for some strategy.
