Will this game run in my laptop or PC?

I'm not an avid gamer but I do like to play a few games on my computer. The only game I finished was Fallout 2 and I was in high school back then. On Gameboy Color, I finished the Pokemon Yellow. In my iPhone, I finished Need For Speed Undercover. Those are the very few games I finished.

Fallout 2 is a post-apocalyptic game - This is the future of Las Vegas (?)

I like playing the game Grand Theft Auto, particularly San Andreas. I've played Vice City too. I wanted to play GTA IV but it's not compatible with my laptop. That is also part of the reason why I wanted the Alienware M11x!

Question is, before buying the game and upon checking the minimum requirements, there are no guarantees that the game will work on your system. Yes, I've experienced that several times already. I have discovered this website that checks your system whether it can work or not.

For example, the link below is to test whether Grand Theft Auto IV will be playable in your current system:

There you go. If you want to check first if the game will run on your laptop/ PC, check that site out! Below is a screenshot of the Yougamers website
