I've also seen a case where a partial memory implementation didn't use the
full width of the memory data bus. But it is something that an aspiring
3D'er needs to be aware of.

BTW, this is a very recent card, but it does support interlace.

Just wait 'til you're watching your 1280x1024 3D video at 43 Hz interlace and
16 colors instead of 75 Hz progressive and 256 colors because you didn't know
to buy that extra meg of memory, and see how unrelated to 3D it is. ;-)

OK, OK, back to some different 3D - I went to a local Little Caesar's, and
they didn't have 3D glasses. Is that just in Canada?
