Ok, I remember reading the answer to this somewhere but I can't remember where. For Crossfire for the X1950 Pro, I can just add another X1950 Pro, doesn't have to be the same brand right? I have an ATI branded one right now (and am pissed that they go on sale a week after I buy mine) but I'd rather spend the $75 less and buy a Sapphire when they are in stock again.
