ATI/AMD Catalyst 9.3 seems to be the end of the line for updated drivers for many DX9 chipsets.

I discovered this one by accident when trying to use Mobility Modder to update an older laptop running Windows 7 to run the latest Catalyst drivers. Unfortunately, you can install the new drivers but they will refuse to load with a cryptic "Driver reported a problem." message.

Wonder which graphics cards (desktop, mobile and AIW) should use Catalyst 9.3 with for now?
Radeon 9500, 9550, 9600, 9700, and 9800 Series
Radeon Xpress, X300, X550, X600, X700, X800, X850, X1050, X1200, X1250 X1300, X1550, X1600, X1650, X1800, X1900, and X2100 Series

Unfortunately, that is a pretty sizable group of graphics cards that came out not too long ago.
