I'm using the Nvidia 8500GT. While I've seen many others having problems with it, other than loading the driver it works for me. The issue is the xorg.conf file it seems. I've not got mine up and running at 1080i perfectly. It does have overscan pretty bad, my previous ATI card did not. It is worth it to me to have the alpha-blending.. If you go with this card, load MCE, then when it first boots hit ESC to go to recovery mode, and download the envy package (albertomilone.com). Load the nvidia driver, and keep going into recovery mode until you get your xwindows environment setup how you want, so you can run startx and get into the GUI. I did it this way and it worked fine for me. Once that was working I did the normal bootup, when through the setup process, etc.
