sounds like you are pointing more towards the ROG board, go with your gut feeling on it. i typically find a product that suits me the most then try to disprove it in anyway possible just to make sure it is the product for me.
you are going to spend an extra $30 to get wifi and blu-tooth anyway, might as well just get the maximus. my first choice was a z68 gene-z but newegg was out of stock and i had to settle for a gigabyte board, i regret not waiting for it to be back in stock
i also have a 670, did you get a asus gpu? i chose it because it was the quietest option on the market, after living with a 480 you can probably understand why
