Most Graphic Demanding Games

It's the 21st century and the developers behind every modern-day, next-gen games have been rising and proving their names ever since. Here are some of the games which I have and played that requires top-end gears and rigs for them to run smoothly:

• Crysis and Crysis Warhead: The Turkish brothers from Crytek made their debut in next-gen PC gaming with the new release of Crysis. A game that tells the story of a nano-genetically enhanced character wearing a nano-suit that is task with eliminating a group of terrorist operating in an isolated island. However, little does he know, the island has been overrun by aliens. This game has obviously the most demanding graphic ever created in the history of gaming. It uses the Crytek engine to push the latest graphic cards or VGA cards to their limits. When I first played the game, even with all the good VGAs, Power Supply, and Chipset - I'm still unable to play the game at Ultra Setting or even Very High setting. 
• Need For Speed Pro Street: EA's first legal racing game that was based on the illegal street racing of Need For Speed. This game was my first graphic demanding racing game before I bought Race Driver: Grid. Yes, it has basically the same story as Crysis. I was still unable to reach Very High setting and when a crash occurs, it lags.
• Empire Total War: This installment from the award-winning Total War series caught my attention and most of my time when I first bought it. Since I like strategy games, I was eager to get my hands on this one. But woah guys, this game requires the latest graphic card to run at Ultra without lag. I was able to reach that setting, however, everytime my artillery batteries fire, it lags and the smoke from the musket also caused the lag.
• Napoleon Total War: Same story as Empire Total War. Only this one was a sad story. I was only able to play at High Settings due to the ground and soft particles effect which had been applied within the game. You see, each time a unit moves, walks, or runs, they make this cool dust trail -- which causes lag.
• Dawn Of War 2 and Chaos Rising: This game doesn't have any problem until a huge, maddening explosion occur. Artillery Barrage and Orbital Bombardment mostly cause the lag each time I use that ability.
