i have a compaq laptop with windows 7. mobile intel(R) 4 series express chipset family. ok i don't know alot about this stuff. but i have one proccessor. intel(R) celeron(R) CPU 900 2.20GHz. i want to be able to play fallout new vegas with ultra settings and no lag what so ever. what kind of graphics card would i "NEED" to do this.
I don't know anything about Fallout New Vegas so I don't know what the requirements are, but since your computer is a laptop, I doubt that there is much you can do to improve your experience other than getting a more powerful computer or playing at lower settings.
