I have always said na-vid-e-a
 
But I could also see N-vid-e-a  with the N being short.
 
How is it said?  

N like the letter n (en)
vidia like video but ending with a short a (vid ee ah)

eN - vid - e - uh

I can't believe we actually just replied to that...

now maybe I wont look so stupid when talking to people.  lol

 
 
honestly, I can't believe I couldn't figure it out...
 
my eng 102 teacher though mogly from the jungle book was pronounced mougly.  He had only ever read it, never saw the movie.  

It is mougly, isn't it? I could swear that's what I remember Baloo saying. Heck, I probably didn't spell that right either.
 
And everyone's worried about us american's not understanding tech support reps anymore, we can't even understand ourselves.

The simplest way to know is to fire up Bioshock and listen to the girl whisper it to you.
 
And I remeber it was pronounced Mougly....

I pronounce it Nvidia, just like the box says.
