I'm biased, but meh.
I'd say neither, although the ASUS one I bet is fine.
I would go for a DFI LanParty UT nForce 4 SLI-DR
Its alot pricer, but i've used it before and its amazing. Its so stable and reliable, and it works out of the box with no problems. I can also say the same thing about my LanParty motherboard even though its s754, AGP, and uses the nForce 3 chipset.
Its been a long time since i've used an ASUS board, and I don't remember what i thought of it.
Don't buy Abit boards, their trash. I know someone who has the one you listed and he's constantly having problems with it.
EDIT: even though you don't plan on doing SLI, it doesn't hurt to buy a motherboard that can do it.
