Can more system RAM compete with video RAM?

    Two laptops, both have celeron m 1.4GHz processor and 256MB
    DDR ram. One has a video card with 32MB video memory, the other
    has a video card that shares the system memory (max 128MB).
    My question is: generally speaking, if I add 512MB system memory
    to the laptop without the video memory, can this laptop overperform
    the one with the 32MB video RAM in terms of graphic and video
    process, or it is hard to say?

    No, the system with the dedicated video memory will (99.9% of the time)
    outperform the shared memory system. It has to do with the speed at which
    the video system can access the memory and shared-memory systems typically
    will access the memory much slower than the dedicated ones. Adding more
    memory means the shared video memory may be able to run something that has a
    higher ivdeo memory *requirement* however. If you got a game that needs 64M
    of video memory and it queries the 32M dedicated video, it may just not run.
