Video Card

Ok, so I've got my mind set on this laptop I'm anxious to buy. However, my limited expertise with matters concerning computers has really got me confused. Anyways, here's some specs:

Intel Centrino Cor 2 Duo P8900 (2.27 GHz)
4GB DDR2 RAM
500GB Hard Drive
Nvidia GeForce 9600GT Graphics (256mb)

Very good, I think. But I'm afraid of whether the graphics card will drag the whole system behind in gameplay performance. Will it?
:dizzy2:

Please guys, I humbly ask for your expert opinions. Help. Thx in advance.

EDIT: I think I made a mistake. I believe the graphics card is 512mb. I DON'T KNOW!!! HELP!!!
EDIT2: Nvm. Go to my other topic!
