You can get This Machine during the unmarked quest Dealing with Contreras. It is givin to you at the end of the quest by either Daniel Contreras or Carrie Boyd depending on how you complete the quest.
All around best gun for me would be 'This Machine'.
Fallout: New Vegas
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
That CPU is sufficient for Fallout: New Vegas. Generally any decent multi-core processor will suffice. What is of importance however is the amount of memory or graphics card your machine has.
In my opinion, Fallout 2.
Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.
fallout: new vegas 2 I've heard.
Nothing in New Vegas spoils Fallout 3. They take place in 2 completely different corners of the country. And New Vegas can not spoil anything for Fallout 3, as New Vegas takes place before the events of Fallout 3. Hope this helps! Also Fallout 3 is not a sequal. But lets pray for a Fallout 4
New Vegas is not an expansion pack for Fallout 3 or part of the game! Fallout: New Vegas and Fallout 3 are separate games. As for "how to get there", you can purchase it almost anywhere retail video-games are sold.

No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
"Fallout: New Vegas" is projected to come out sometime in 2010.
