Not a direct answer to your question but it might help. I have the GTX 285 and works perfectly fine with Inventor.
If you mean what is found in 2012 and later, I cannot answer directly as I am still on 2011. I would assume so though.
I should be moving to 2013 after SP1 is released.

From what I have seen, it seems that the GeForce cards are a better option for Inventor these days. I have been directing customers towards them over Quadro and FireGL cards.
I almost always use the driver from the card manufacturers site over the drivers that Autodesk lists on their website as well.
