Why? Did Ageia promise you in writing that your card would be completely functional for a certain period of time?
when you purchase a product, you are purchasing the ability to use that product indefinitely, in any way shape or form, unless a user agreement or other TOS puts restrictions on that use and the purchaser is made aware of it before purchase.
there is no such restrictions put on the ageia physx cards. the seller (or company that bought out the seller) would have no legal right to tell me when i can not use the card. it was never brought to my attention at the time i handed them my money, that the card would be rendered inoperable on purpose if used in conjunction with unapproved other hardware.
so to answer your question- by not explicitly stating at the time of purchase that the card would be rendered nonfunctional *on purpose* sometime in the future- yes ageia promised me that the card would be completely functional.
@GotNoRice - thats what i figured, you would just have to download older drivers. i dont currently use the card, so im not that interested in it, however it does get under my skin when a company tells me what i can and cant do with my product that i bought at any time, but especially sometime after purchase, which i did not agree to.
