And how about the X68 chipset? Will we be again restricted to a dual x8 mode in sli/crossfire? I'm planning on running 3x24 monitor setup by tri sli/crossfire which will be bottlenecked at higher resolutions. I wish they go with 16x 16x 8x, or better yet all 3 16x pcie. I could have build a 1155rig w/ AsusM4E but I would like to use a discrete soundcard, as I don't like the integrated one.
Actually The LGA2011, from what I can find, will be hosting 40 PCIe 3.0 lanes. One PCIe 3.0 x16 lane will be 2x as powerful as a single PCIe 2.0 lane, much like it takes a PCIe 1.0 x16 to equal a PCIe 2.0 x8 lane. So with 40 lanes you would run at x16/x16/x8 which would still give better bandwidth than a full x16/x16/x16 PCIe 2.0 setup.
Still there are no real GPUs out there that even tap the full bandwidth of a PCIe 1.0 x16 lane apart from dual GPU boards, even then. Hell LGA2011 is not even set to have Intel HD graphics. its set to be just the CPU itself.
As for overclocking, its hard to say. I am sure it will have the same setup as LGA1155, with all the parts being on die and tied to the BCLK but there will probably mainly be unlocked versions since high end is always known for overclocking.
As for discrete sound, you can always use a discrete card. Just disable the onboard in BIOS like I did when I got my Creative X-Fi.
The other advantage that LGA2011 will have is tri channel DDR3 so memory intensive applications will love it. Supposed to have something like 51GB/s bandwidth for memory due to it using QPI and the third channel instead of DMI 2.0 and dual channel. But other than memory loving applications, LGA1155 will probably be a good setup. Even with just x8/x8/x8 PCIe 2.0 it would be fine as there is pretty much no difference between that and full x16 PCIe 2.0 on current GPUs and probably wont be until a good while.
Hell AGP 8X was not even bottlenecking when PCIe 1.0 came out and probably didn't bottleneck until the nVidia 8 / ATI HD3K series really.
