PC - PCI Express 3.0 - View Post

Since PCI-E is being discussed, I figured I'd ask a question.

My mobos PCI-E 2.0 does 10GB/s per card in SLI mode(standard 16x) but when adding a 3rd card, two of the PCI-E ports go down to 8x speed. So its 16x 8x 8x in tri sli...

The video card I have scales pretty well in tri sli according to reviews (20-30% performance boost). However considering the fact that the 2nd and 3rd PCI-E is going to be only 8x...is it worth adding another graphics card?
