hello im looking for a video card that has crossfire or sli built in, as the 2 pc games i play have crossfire and sli support. so far the only card i know of is the 4870X2. are there any other ati/amd and nvidia cards like this that have dual gpu's on the card.also as far as for ati/amd and nvidia is there an easy way to tell which cards have dual gpu boards so this topic should include all dual gpu cards past and present also they have to be pci express
