I am trying to find a list of 8800 cards that work in a 1st gen mac pro. So far it seems some evga, pny and xfx cards work. Any other brands? The card I am interested in is the ECS card with passive cooling. http://www.newegg.com/Product/Product.aspx?

I think it would be really great to have a passive cooling card which is much faster than the 7300gt card. Thanks.
