NVidia Recommended Graphics Card For Doom 3

Griffon4 writes "Nvidia announced today that they have been branded the recommended graphics card for id's forthcoming PC FPS Doom 3. Now I'm wondering: Recall a little over a year ago that Carmack said the Nvidia card at the time was just a slight bit more worthy than the ATI? Jump forward to today - are we getting a real recommendation based on id's own experience or just seeing the end result of a financial deal that benefits both?" Other possible factors (apart from NVidia simply being the better graphics card for Doom 3) include the alleged origination of some Doom 3 Alpha version leaks, unlikely to endear ATI to id, and, of course, ATI already having a major bundle deal in place with a certain other FPS.
