There are no Windows 7 drivers for that card. You can try to use the Vista drivers, but no guarantees.
Hi I have the same videocard and Win 7 (runs okay) and was looking for a more recent driver. I recently moved house, but I have the disc boxed somehwere..
I had a closer look at the AMD site and I think you need to look at graphics / legacy / ATI Radeon X series / X1xxx series (submit)
then there are 2 downloads Catalyst an WDM
The Catalyst Control Center is to update and fine tune you video card?
The WDM is for video output when Windows says it's missing a few drivers?
mind the useful info on the AMD site about uninstalling the previous version before installing the next
It's a bit late in the evening for me now to test them
