Good luck with ATI. The rumour is that Nvidia is going to get working with AMD. That makes it a partner for both Intel & AMD. Tough times ahead for ATI (Good, I hate the bstards!).
I've had my 8800 for almost a year and have never had any problems with the drivers. Every game I have new or old worked just fine even with two updates old drivers I had before I remembered to get the new ones month or so back.
