New video card has AIDS

I just got my new 6800 AGP video card today.  I bought it off newegg.com.  It's this one right here
http://www.newegg.com/Product/Product.asp?Item=N82E16814121216

I installed the drivers at first from nVidia's website and it works...just not on games.  In games, everything flickers and some of the text on menus is gone to the point where they're completely unplayable.  Then I tried the CD that came with the card, but that just gets my comp stuck in 4 bit color.  Really frustrating.

Anybody have any ideas as to what this cold be?  Is it my MoBo or could the card be defective?  I really don't want to have to return it to newegg.

fail. I got one of those years ago and because of the AGP interface I can't justify upgrading my processor to a dual core, because there are no decent boards that support agp anymore. You should have upgraded your board and processor while you were spending $300 on a video card anyway
