Hi all! I was wondering why so many people use ATI graphics cards when most of the games I see are optomised for nVidia? I've never used an ATI card myself (except for an ancient 2mb 3d Rage II +DVD pci card), so I am just curious. I am also going to use some of the money I'm getting for Christmas to get a new graphics card, so I want to know some facts before I choose what brand to buy.
