We recently explored Sapphire's FleX edition of the new HD 6770, a black sheep in the new Northern Islands family still running on a Juniper-based core. Though it has a great value, the true entry-level cards for the 6xxx series are the 6450, 6570, and the 6670. Today we'll be sitting down with the latter of the three, to see if Sapphire adds a little extra value to the package.
