Whats the difference between these two Mobo's

Where is the $40 difference in these two motherboards?http://www.newegg.com/Product/Product.aspx?Item=N82E16813131011http://www.newegg.com/Product/Product.aspx?Item=N82E16813131163They have the same model number and only minor variations in the features as far as I can tell. I'm assuming its the Vista premium package thats is the source of the difference but I don't see any details on the product page let alone info on any aspects of it that would make me spend $40 plus the price of a wireless network card to get it.Whats the difference between these two Mobo's
seems to be some small differences as far as SATA connections go but the main one seems to be one comes VISTA READY........ :roll:Whats the difference between these two Mobo's
the only thing ive really seen is the $200 one has an external SATA connector. It also has more RAID options.
