I am in the process of changing my PC, my AMD64 3500+ has served me long enough and it's time to give it to my wife

That PC will be a dual boot between XP and probably the upcoming FC10.
It will get some Raptor, 4 GB of RAM, a Q9550 and a GTX260 (+ or not depending on availability).

As the title suggests after some browsing, I have decided I would go for either Gigabyte EP45 DS4 or ASUS P5Q Deluxe.
What can I expect of Linux compatability on both these motherboards ? Network, sound, SATA and so on?
