Abit, Asus, MSI, are all brands to consider plus a few more. Personally i like Abit, but i heard MSI is right there too. Decide what you want and what you can afford and it should point out one of them over the other
I agree that ABit and MSI have good boards. Especially the MSI Neo2-Platinum, I was fairly impressed with it and it's rather extensive BIOS menu. I don't like ASUS though BLEH!
EDIT: BTW you're going to need awful good cooling if you want to OC those chips. I don't know how good those OC. There's one core in particular, the Winchester core I think it is that OC's a little better than the others, but I'm not sure which CPU's that core is made for. Other than that nothing overclocks better than an XP-Mobile barton core
