macbook video card help

Hi people....i am from brazil and want to buy a macbook ....but worried about video card memory...does it use shared video memory? (from the main memory) if so...can i allocate more or less memory for the video card? the questions coz i play flight simulator and its important issue for this game.
i could buy 2gb of ram and alocate 512 for the video card?

gotta know this cause this computer costs more than twice the price it is in the usa here..

thanks

Welcome here, mtsm.

Yes it does.

I don't think you can.

does what? allocates main memory for the video card? what's the amount of memory it allocates? isnt it possible to allocate more or less memory?

It's all in the specs that I linked you to. And I don't think you can allocate more memory for video RAM.

My Macbook can play World of Warcraft just fine, so its better then people say. Depending on how new/old the sim is, it may run fine.

My macbook plays Halo, Half-life 2, Sin: Episodes, and Unreal Tournament 2004 just fine. Of course, it plays flawlessly when i crank down the settings and play in windowed mode.
