    ...I would like to chime in with a "me too" on the subject of "just
say no to ATI cards".

    I have used ATI, Intel and Nvidia cards in my myth boxen and by far
the best results I've gotten were from the nvida 6xxx and 7xxx cards.
I've also had good results with the intel gma950 in the minimacs.

    My worst performer by far was the ATI onboard chipset.

    None of my mythboxen have included a "normal" video card. They
have all used "onboard" video of some sort.
