Here you go. ATI 5.12s CP ATi is just ahead of nVidia in driver development for windows Vista. From what I understand all drivers for Vista have to be built on the .Net framework.
Wont care till some time after it ships and there is proper driver support. Took almost 9 months for XP to get to that level.
Right now... my only concern is having a video driver that does not require me to BLOAT my otherwise fast system with bullshit in order to update my system.
