Yup that's the one I meant. And yeah it's made by Seasonic, most brands don't make their own stuff.
If you are only running a single HD7870 you only need 500W, any of the similar iterations of the previously mentioned PSUs in the ~550W area will be perfectly fine.
Yeah it depends on what you are using it for, but if you do need 750W (mid-high SLI/Xfire setup) then it's a very good PSU.
As for value, Seasonic are rarely going to win the best price, but it's still a good deal.
Other slightly cheaper options that still offer 80Plus Gold and modular cables -
Rosewill Capstone M 750 - $120
XFX Black 750 - $130

As I said this should be fine if your doing both, cf, and ocing at the same time. For only one it should run exelent be able to take what ever you over clock. Its is a really high quality psu
