So I heard a rumor that x58 motherboards can only utilize up to 36 pipelines. Meaning that if someone had a board that supported x16 x16 x8 SLI or Crossfire, it would actually downclock one x16 to x8 in a tri-SLI or Crossfire set-up. Is this true?

In either case, what's better?

definitely having all the slots at x16 would best them all. though you cant fail to pay attention that x8 and x4 only have 2% and 5% perfomance difference respectively with x16.
therefore it comes down to SLI/CF scaling. 1 card, 2 cards, tri or quad? which scales better with the 2% in mind.

I already knew that AMD/ATI cards wwere very good at this but would like to see the same tests done for Nvidia cards.

Is this really a question? I mean common sense tells you that 16x/16x is the way to go. Which is why those boards cost more.
