What programs do you see the cards at idle? some games don't support crossfire at all. Also make sure you run your games in fullscreen, not windowed for fullscreen windowed.

Also GPU usages?

you are much better off with a single gpu, especially with your processor


you can grab a 7950 for almost nothing nowadays
