In what ways is the NF7-S better than A7N8X-E for overclocking?

Everywhere I go I see people saying that, and I've seen one reason: the vcore and vdimm on the Asus are limited. Other than that, is there anything bad about the A7N8X-E? Does the FSB/northbridge have the ability to go to the same speeds as the FSB on the NF7-S? I bought one today because the store was out of NF7-S, and since I havn't had a chance to open it yet I'm wondering whether I should go return it and wait for the Abit to come in, or whether I can just go ahead and open it up for some overclocking. I'm looking at maybe going to FSB speeds 210+ because I've got a locked barton. If not, the minimum I need is 200.
