I used to know all there was to know about graphics cards. But in the year and a half I have been away from coputers everything has changed. I bought doom 3 finally and need a card that can handle the game. My lcd has a native rez of 1024x768 and I would like to run the game there. I am confused on rather a x700 with 256 mem would run the game where I want to run it at. Also what is the performance difference between the x700 and the x800. (not the pro). One more thing, Would an AIW card take any of a performance hit because of the extra VIVO features.
