I have a AMD A8-3870K APU that has AMD's DualGraphics feature. This means that you can run in 'CrossFire' with another GPU. My question: Will this feature also work with a Radeon HD 6000 series GPU from a different brand? For excample, I saw a Asus HD6670-2GD3 graphics card which is a Radeon HD 6670 card. Will this one work with this feature?
Exactly what Pip/Double said, AMD does not make any of their cards in house, unlike Nvidia. Any 6670 That you get should work (Asus, XFX, you name it.)
