There are two options for download from the AMD site one is just driver and the other is the whole catalyst suite. So you can just download the drivers then find another utility for thr higher functions. In the past i haev run with just the drivers and ATI Tray Tools, i dont run dual monitors though so dont know if ATT has support for that or not. http://game.amd.com/us-en/drivers_catalyst.aspx?p=vista32/common-vista32
Thats the link to AND drivers you just need to pick the correct ones for your system.
