the specs say:

64MB of DDR2 SDRAM shared with main memory (2)



but the note says:

Memory available to Mac OS X may vary depending on graphics needs. Minimum graphics memory usage is 80MB, resulting in 432MB of system memory available.





So is it 64mb or 80mb? And can it use 'more' since this is the minimum?

    It shares the CPU ram and will toggle based upon need.

    ok, but shouldn't the spec say 80mb minimum instead of 64mb? And can it use more, say up to 256mb?

    The on-board graphics use 80 MB minimum of which only 64 MB is used as video RAM by applications and the GPU's frame buffers.
