Physics card? Who needs a Physics card?

Has anyone read this article? Surely something like this would be able to outperform anything that companies such as the like of PhysX would put out. If anything, the sheer computing power that that has would be able to make the most realistic physics ever concieved. The neatest thing is, the actually plan to make one for the PCI Express! That means, in probably a year or less, there will be the opportunity to make the best experience that an enthusiast can have, without having to buy a server system.

But at the (possible) 5000-6000 dollar range, who will buy it in this segment? That would easily double the cost of a high end system, and it would multiply by 10 the cost of some low-end systems. Anyone think they would go for one eventually?
