Abit without a doubt. Asus has slipped in quality over the last year.
Finally someone else see's that ASUS is slipping....ASUS sucks man.....if you speak taiwanese then you'll have no problem with tech support otherwise you are screwed.
Asus gave me a lot of problems regarding hardware compatibility believe it or not with a videocard recently.
Wong is completely right...this is why I bought my current MSI board because when I tried installing my FX 5700 256mb card it'd freeze and I've already helped about 4 other people with similar problems on ASUS boards...they suck now and aren't all they are cracked up to be. It seems ABit is the way to go for stability and compatibility reasons, not to mention great OC'ing options.
I see asus used for gaming more though, i also think abit has more to do with intel than asus. Just a thought.
....any motherboard can be used for 'gaming' and abit doesn't really have 'more to do with intel'.......ABIT makes boards for AMD...as simple as that...but yes you need to get the NF7-S2...if you go to zipzoomfly.com when you order the NF7-S2 for $77 they'll automatically upgrade you to the next board up...the NF7-S2G which has a gigabit lan card installed and is just the next version board.....make SURE you get NF7-S2 and not NF7-S that's how you know you got the right version.
If you go ASUS I'm gonna say the chances of you having some sort of problems with it will be 70% but that's only my opinion. Thankyou Agex...finally someone has realized that ASUS is no longer a supreme quality maker board. I don't know what is up with their boards and not wanting to accept compatibility between the previous generation cards, but I went to their customer support and a guy named 'ZYC' from taiwan writes back
'You need new card...some motherboards to new for cards...you need send back your card and get new one'
I replied 'Screw that, its your sh!tty boards thats givin me the trouble not the card'
I put the card in an older and less known motherboard company (Azza...anyone hear of this?) that my friends computer has and the card worked fine...but not in a newer ASUS board with nforce chipset? Right....anyway...hehe..enough rambling.....get Abit.
Check it out, here's a link to the version you'd want to get...the NF7-S2....and it's the link to zipzoomfly and they still have the offer to auto-upgrade you to NF7-S2G

EDIT: Not that this needs to be longer, but yeah the ABit board you linked to isn't the 2nd version so DON"T get that board you need the one that says NF7-S2 or atleast NF7-Sv.2 or something to that effect
