anyway, as most of us wont use 3 way or even 4 way its more or less a hypothetical discussion. but if somebody with three cards at hand is willing to test this for us i'm curious to see the results.

ps. still waiting for my cpu and ram, so cant test this myself right now. besides that, my old cards wont support 3 way sli, so i'm lost here anyway ...
Don't worry, I won't.
Just came home, moved my GTX 480 from slot #1 to slot #2 and what I found out is that bassplayer's statement "Slots 2 and 4 are hardwired for x8" is absolutely right.
I'm not sure about configurations of lanes when using Tri-SLI and could be wrong. I just might not remembered correctly, but anyway it would be a little stupid if MB could not re-route lanes to be 16x-8x-8x and run @ 8x-8x-16x, when it has 32 for those 4 slots.. Why the fcuk would I need third card running @ 16x
However, this will probably stay a hypothetical discussion as you said, if someone doesn't step up with 3 VGA's to test.
