Its not required, however if you have a DX9 video card with pixel shader 2.0
support with a decent amount of memory, and proper driver support you can
use the Aero Glass theme.

Don't upgrade your video card unless you want better gaming performance,
Aero Glass is not worth the upgrade.

The minimum requirement for vista seems to be 128MB video card. Would I gain
any functionality by going to a 256MB card?
