in general, what benefit does more video ram give? i have a P4 with onboard video that is configurable for 4, 8, 16, 32 or 64 mb.

do the features and capabilities of the card become disabled if lower vidram is used?

so only 3d performance is affected? what about resolution and color depth? the pc will be used to store/view high res photos. thanks for the quick reply.

you do the math ;)

highres = 1024x768 ?
colordepth = 32 bit ?
so memory needed=
1024x768*(32/8)
I don't have a calculator here

1024 x 768 x 32 bits per pixel = 25.165.824 bits.

25.165.824 bits / 8 = 3.145.728 bytes.

3.145.728 bytes / 1024 = 3.072 KB.

3.072 KB / 1024 = 3 MB.

You will need at least twice that quantity for page buffers / buffer flipping, etc.
