Hi!
In the final version, for sure, Windows Vista will support your graphic
card
with Aero. Your graphic card is very great one.
But, not in Vista beta 2.
Download this program :

Run it and you will see that your graphic car is not yet supported by
Windows Vista Beta 2.
A friend of mine, having the same graphic card as you, run the Upgrade
Advisor on Windows XP.
Upgrade Advisor said to contact manufacturer of the card to have the last
driver.
And, here
http://download.nvidia.com/Windows/88.61/88.61_ForceWare_Release_Notes.pdf
you will see that your graphic card is not yet supported by the
manufacturer
in Windows Vista Beta 2.
I have the ASUS 7900GTX graphic card and Aero is marvelous.
As you graphic card is better than mine, your graphic car will support in
the final version of Windows Vista.
Have a nice day! Roger
