At most you are looking at a couple of percent. Nothing to worry over.

Not at all (or very few so not noticeable). You have no bottleneck in your PC.

AFAIK, SLI is "officially" supported on x16 and x8. so unless there is some voodoo magic with hybrid SLI; i am not sure exactly how they got those numbers.

on second thought if they limited an x8/16 slot to x4 speed but SLI still read it as x8 . . . still it begs the question: would you still get enough gains to warrant the cost?

I wouldn't consider putting a third card in a 4x slot, sure it will work but you would loose some performance. I would personnally choose a motherboard capable of doing x16/x8/x8 at least.
