Brand doesn't matter at all... neither does which pin you use - there are actually two pins per card so that you can crossfire three cards if you so chose to

My question is
a.) is this true?!?!
b.) if so, which crossfire pin do I use - the one closest to the middle or the one on the edge???
On a side note, does it matter at all if the cards are from different manufacturers? (in my case, MSI and Gainward)
