Sapphire 7870 or AMD 7870

I thought i had ordered the AMD Radeon 7870. But today( about 2 weeks after receiving it) i saw it was a Sapphire HD 7870 GHz Edition. Should i return it for the AMD? And does it lives longer? 

AMD outsources the design of their cards to different manufacturers. Sapphire being one of them. What you got is one of the better made 7870 cards. You're fine.
