Ultima 90 good for passive on an undervolted 4850e or 5050e?

[Hard and Confused]

Anyone have any experience running an Ultima 90 passive on a 4850e or 5050e? If so what are your results?

Yes, I'm using it on an i7 920 actually due to the size of my case and it works just as good as my TRUE 120.

I'd buy another one but they stopped making it and no one has any left in stock.
