Default Gigabit Lan

Is PCIe Gigabit Lan any different performance wise then just Gigabit Lan on the motherboard

I know that a plain PCI gigabit NIC can max out the PCI bus (along with everything else on the bus) but PCI express gigabit card cannot max it out so if your onboard is using then PCI bus then you will noticed a big difference THEORETICALLY. However, in real life there will be very little difference, maybe a little offloading of the CPU and a bit better pings but nothing huge.

Yes I'd pretty well agree you summed that up.

even gig lan doesn't mean much especially if through traditional speed router

But within a Lan doing file transfers it may mean a bit more throughput possible
all items being equal.

Pretty much all Gigabit ports on motherboards use PCIe already so I don't see how using an add-in card would be any different.

And well if your router/switch isn't gigabit, there's really no point. Even if they are, your hard drives are the bottleneck IMO along with the OS's file sharing.

Depends, the Marvell chip used on most motherboards(even high end ones) is, to be frank, crap. Assuming your onboard network is powered by one of those chips, PCIe or not, then chances are that replacing it with a PCIe card based on an Intel PRO chipset such as the Intel PRO/1000PT will improve your inter-network performance.

That being said, while it will lower you CPU overhead, and margnally lower ping rates, it will not change the perfomance outside your network(ie, the InterWebs). Your HTTP/Bittorrent speeds will laregly remain the same, your gaming experance will largely remain the same, pretty much, everything will *seem* to remain the same.

Very few people would be able to tell the diffrence. Sure the Intel card could possibly lower your ping by 2-5ms but chances are, except in benchmarks, you'll never know/notice it even if it did.
