Don't know, I just saw it while downloading a driver.

I don't know about performance, but what I recall is that the problem is that it sometimes can take the card a second to ramp up to full speed which vista equates as the card stalling so it kills the app. I knew it was a problem with the 8000 series but not with the 7s or 6s, but it makes sense since all of them runs at different speeds depending on if its displaying 3d or not.
