OK...here's the deal...I'm confused with something about crossfire. According to the chart located on ATI's website, (here: http://i10.tinypic.com/63h3j8m.jpg ), what kind of card do I need for crossfire? I have a Connect3d X1900GT (574/600), and from what I've read, I need a CF edition card...but according to the chart do I only need another X1900GT? If just another X1900GT is needed, the brand doesn't matter, as long as the specifications match up...right? Sorry if this has been asked and answered 100 times, but I couldn't find anything matching my question on a search. Any other info for a Crossfire newbie would be appreciated. Also, I have an Asus M2R32-MVP mobo.
