From those four MOBO how would you rank them? I do intend to OC to some extent so that is a factor. I will also be crossfiring two 6950's but not right away. I believe I picked only the ones that supported two 8x speeds when using both x16 slots.
Thanks for the input, after slowing down and going through all the specs you guys are correct the PRO will be just enough for me and I dont think the extra money justifies the extra features that i probably dont need.
