I was just listening to the pcper podcast and they discussed performance between the 6990 and the 580. They also had an article to see the results, they use two alienware machines for their tests/ comparison thought I'd share the info, here's a link to the article.

This is a timely article for me, since I am facing this dilemma. PhysX looks great, and Optimus would be useful, but are they worth an extra $300 versus a card with otherwise equivalent performance? I'm thinking no.

I went with the 6990m, $300 more for Physx and a few FPS isn't worth it for me. With the next gen coming in the not so distant future, I will go with ATI. If Nvidia puts something out, and it rocks I will upgrade if I can in the future.
