i have an ATi 9600 pro 256mb and haven't had a problem with it, Nvidia may be a better brand
but with that comes price too. I'll stick with ATi
I'll stick also with ATI. My onboard chip is ATI.

I don't want to buy a nVidia card and have troubles afterwards with some conflicts between the ATI onboard chip and the nVidia card.
ATI for life?
