Have you seen 8800GTS(g80) and HD2900XT for Mac pro(1,1-5,1)? Just now I saw them on an online store. As I konw, the video cards for Mac pro(1,1-5,1) are 7300gt, 8800gt(g92), HD2600xt, X1900XT, Quadro FX 4500, Quadro FX 5600, GT 120, HD 4870, HD 5770, HD 5870(These are listed in Mac pro page on wiki), GTX260, GTX285, GTX680 and HD7950. I have never seen 8800GTS(g80) and HD2900XT for Mac pro before. But these two cards seem to have the features of Mac pro video cards. For example, they don't have the VCD port. Can that be ture? Or I am just ignorant?
