[gkay09]

Oh my God...I didn't notice this till now..
Out of my own stupidity I bought this video card already - http://www.canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=018942&cid=999.243.272

Do I need a mobo with 2 x16 PCI-E slots to run another card in crossfire?..Cant I use the following board for crossfire with this card?..

And should the second card also be from the same manufacturer with PCI Express 2.0 x16 interface?..

Thank u..

You can choose any of those mobos you want...The board should have 2 pcie slots and should support xfire thats all...
The second card neednt be from the same manufacturer...
