    Onboard Lan not on PCI Bus??

    The onboard LAN on the P4C800-E is the Intel CSA LAN, which takes it off the PCI bus and so I'm wondering what exactly does this mean in terms of overall system performance as compared to the 865PE Asus board?

    It can mean higher throughput if you're running a true giga-bit LAN...the PCI bus is shared, and slower, and slightly more CPU intensive. If you have several other PCI cards sharing that PCI bandwidth, and you're dealing with lots of LAN transfers over giga...it can start taxing performance a bit. The Intel CSA LAN doesn't have this limitation.

    For the average home user, even hardcore home user or gamer...a non-issue, 99.9% of home LANs don't run true gigabit.
