Ive read a couple of things which suggest that this... http://www.overclockers.co.uk/showproduct.php?prodid=MB-135-MS supports both crossfire and sli, can anyone confirm that this is true? And if so what is the crossfire/sli speed is it 16x 16x? All seems a little to awesome for the price so my final question is what is this board like? any good?
