    Hi everyone,

    Started a thread here outlining a problem that will most likely be occuring in the D900C and Alienware m9750. Both use Intel motherboards that limit the second PCI-Express slot for SLI operation to x4, down from x16. This can cause a 10% performance hit overall compared to using two AGP 8x cards in a setup used by Anandtech. Like the ASRock board with a VIA chipset, the Intel motherboard chipsets such as the 965 used by the D900C are limiting the x16 spec'd second PCI-Express bus to x4 bottlenecking it in high resolution games. So it seems at least. I can't confirm this, but all signs point to it. Can anyone confirm/dispute this? I really want an Intel based notebook, but not if it kills the point of getting a SLI setup. This seems to be an issue nobody's bringing up.

    Here's the thread I outlined the problem and there's links to news articles and benchmarks of this described issue:
