The video card market has changed very little in the last two years as NVIDIA and ATI have released new versions of their first DX10 video cards with slight changes in features and additional performance. NVIDIA launched the 9800GTX card on April first, one of the weirdest yet truthfully iconic launch dates in recent history. As we all know, the 9800GTX is basically a modified 8800GTS 512MB card with higher clock speeds and a higher price.
