That is a load of complete BS.
Well, the card IS expensive, and it does not really do much right now. The future might be different.
But I wanted to comment on the attitude.
The Ageia card is only worth about $75 to me. Does it make the characters fall differently when they jump? Do they dodge and weave away from fire better? Will it allow me to see in infrared or ultraviolet ingame like the Predator so that I can stalk my opponents? No, No, and (sadly) No. The card does make extra onscreen garbage, debris, and greebles.
Well, going from 800x600 to 1600x1200 with anti-aliasing does not make characters fall differrently when they jump. Nor do they dodge and weave... on and on... blah blah blah...
It is called "eye candy." I would not buy one. But the type of person who would spend $1000 on a pair of video cards is the same sort of person who is the target market of the physics card. I am not saying that those people are sane

and I am not saying that there are a lot of them. But they do exist.
