Sapphire x850xt confusion!

[specialk12882]

What is the difference between these two models of the x850 xt besides the price? The only difference I can find is the SKU number which is

SKU#100103SR-RD

and

SKU#100103SR

respectively.

I'm afraid of buying the cheaper one - I don't want to find out later it was the "Atlantis" version or someting. Thanks for your help!

They are both Sapphire, and strongly appear to be the same cards. NewEgg is really ripping off.
