That's one thing for sure! If you look back at ATI cards before AMD bought them out about every other new model series would see the discontinued support for the older line. Once the X1xxx series was out the 9xxx were dropped for anything past the Cat. 6.1-6.5. That was reversed once AMD was in charge!

For the AM2 board here I had to use the MS updates or go direct to NVidia for the 570 chipset when 7 was first out in beta just to see Vista drivers used then for the one socket series newer board then what AhmNee runs there!

I still have a few XP boats I was to try 7 out on one also a 939. but forget the skt A(462). That one was still able to run 98 there!
