I want to know if the card above is actually the radeon 7850.
I'm thinking of getting that in stead of this:

And would like to know if it is worth the price difference. Also just now when I grabbed the link, i noticed the 7790 actually dropped $10, so now the price difference is bigger.

Im shopping on amazon because im a prime member and i have credit
