Will onboard gigabit ethernet help a cable connection?

[RalphTheCow]

Does it matter at all to connect to cable internet via onboard gigabit ethernet or 10/100 ethernet?

I would think the bottleneck is definitely elsewhere, but then again I really have no idea of the details. I'm just trying to rationalize building with an ASUS mobo with GB ethernet versus buying a Dell with 10/100.

For a cable modem, even an oldschool 10Mbit 10BaseT card would be good enough. The most you're going to see with a current cable modem is 5 Mbit, maybe 7Mbit. A 100Mbit 100BaseT card would be way more than enough. A 1000Mbit 1000BaseT gigabit card is insane overkill.

But I would suggest going with gigabit. Why? Because some day when you have a home LAN, you'll want to move files around as fast as possible. Call it "futureproofing".
