Hello everyone, before I start my question. The GTX 680 x 3 are already on their way, so there's no backing out of it now incase anyone thinking of suggesting any other GPU (670/690/7990, etc...).
I have a Gigabyte GA-X58A-UD3R running an i7 960 @ 4.0Ghz and as mentioned above, I have 3x EVGA GTX 680 (Vanilla) on the way through Step Up and Newegg. Per manufacturer's spec, wth the Gigabyte board, my PCIe frequency with 3 way SLi are x16 x8 x8, while in 2 way SLi, the frequency are x16 x16 (at least that's what I remember it to be last time I read it).
Performance wise, will this be negligble or will it be a bottleneck in my performance? Should I get a new board with PCIe 3.0 along with a new CPU? Or will I be okay with it?
Since PCIe 3.0 x8 (as I was told) would perform on par with PCie 2.0 x16.
I've also heard that with 3 way SLi, I won't be getting the performance bump from 2 way SLi as I expect, probably only +20% if I'm lucky, is that true?
Thank you all for reading and appreciate any input.
