Hmm... I believe you meant "non-essential". 99.9% of the general public use either a single integrated GPU or single Graphics Card. The remaining 0.1% have either cards in SLI or X-Fire and reside here on XS and a few other forums dedicated to spending our savings accounts into oblivion. I'd guess that less than 10% of the multi-card users have a dedicated physX card and probably only 10% of them actually want to use an ATi main graphics card with an nVidia physX card.

PhysX is restricted & only runs on NV hardware anyway so you have no point at all.
Really? Quite a few ATi users on this forum have commented on how they want to use PhysX on their ATi cards, as recently as the post just prior to yours. And while the majority simply want to be able to use an nVidia card as a dedicated PhysX card, plenty of members here continue to say that nV should allow everyone to use their API.

And part of the usage payment would be for driver development and support since ATi users will blame nVidia's "crappy drivers" the moment their nV physX card has problems functioning with their ATi graphics card.

.. I wouldn't be surprised my latter point was the main reason why nVidia dropped their support for nV physX cards with ATi graphics cards.
