SOLVED Differences between the 7970's

I have been looking at reviews, but has anyone seen anything specifically talking about the differences between the different branded 7970's? I'll be using one in eyefinity 5760X1080.

thanks

Looks like the biggest difference besides the fan setups is the Asus card. It takes three slots instead of two, and has 2 dvi plugs and 4 display ports where the others have 1 dvi plug, 2 mini display ports and 1 hdmi.

Thanks for the response! I now see that almost all of the branded 7970's are basically reference design. So I am going to go with the Sapphire!
