Yes your right, I guess it wouldn't overclock much like those with separate Graphic adapters, but some of this boards has voltage adjustment on Chipset that might improve the overclocking capability of the board I guess. Thanks for your post bro...

I think I'll go with Foxconn 6100 k8m8 (

By the way it is priced 3,800 at Insotech, what do you think bro? It is only 3,400 at RSuncomputers.
