    256 is built onto the card so it is in addition to say the 2gb of system ram your computer has

    The card has 256MB of actual, physical memory on it. The card is able to steal 767 MB of system (main memory) RAM for a grand total of 1023MB.

    And the more MB it "steals" the better it will perform for games and applications, right?

    not really its at least 10x better to have 384 mb dedicated than stealing any amount of ram from the system.
    thats because its very slow.
    i think its like when ram borrows space from harddrive which is aprroximatelly 100 times slower. Anyway the gpu you have cant really use more than 256mb ram effectively you will need a high end card for that.

    384MB? Is that off a random number generator??

    wtf?

    its off the binary sequence.

    2 4 8 16 32 64 128 256 512 ....

    128+256= you guessed it 384. Almost every computer part has some kind of reference to that chain.

    It probebly has a 256MB stick of RAM, and a 128MB stick.

    I know, but why would you reference such an odd combination. I have never heard of such a combination and for good reason.

    Edit: Infact even googling for 384MB dedicated VRAM turns up nothing. Maybe he referenced the G80's memory interface by mistake??
