Hey Guys,
I have read everything on Anandtech and elsewhere that I could find on the PLX PEX 8747 chip. I have been researching components for a Z77-based gaming build, which will be a 2-Way SLI setup with dual 680s.
Apparently, from what I can determine, the current crop of Z77 boards which do have the PLX chip (such as the ASUS Maximus V Formula) implement it such that we have one PCIe 3.0 slot running all 16 lanes and a second 3.0 slot running 8 lanes.
My question is this: Given that the two graphics cards will communicate with each other via the SLI bridge, how important to framerates is the use of two 16-lane PCIe 3.0 slots (a' la an X79 board)? My supposition is that in the real world having the second graphics card in an 8-lane slot will exhibit no appreciable degradation in performance compared to a dual 16-lane setup, but I have no benchmarking or other data to support this.
I am therefore soliciting your knowledge and opinions.
NOTE: If you guys know of a Z77 motherboard which does implements PLX with two 16-lane slots, please post on that as well, as it would likely render this thread mute.
Thank you so much! You guys are the best.
