Some good news about Windows 7 for ATi fans, AMD/ATi has managed to get the drivers for the HD 4890 and the 4770 integrated into the Windows 7 DVD.
This could put them a little ahead of nVidia in terms of "out of the box" usefulness when it comes to Microsoft's newest OS. No one seems to know how complete the drivers are or if there will be full 3D support in them.

We are not sure what happens with the previous models but since ATI has Catalyst there is a chance that much more ATI cards will be natively supported by Windows 7.
