question about asymmetrical crossfire.

I don't fully understand how crossfire works. I do know that it involves using two gpus to increase graphics performance. However asymmetrical crossfire uses two different gpus. My question is there a way where you could turn one gpu off? For instance I was looking at a laptop that uses an amd 8650G+8670M w/1gb of memory.

I read that this combo is actually inferior than a single amd 8670M. However, some sites stated on some games, the performance was better than an Nvidia 740m gt. Overall I was curious if I could turn off the 8650G when gaming and use the 8670m while gaming instead of both.

One last thing, I have not yet purchased this system. Im still trying to research this before buying anything.

I believe AMD has a program you can download that will let you disable one of the GPUs, but I haven't bought anything AMD in years so I'm not sure. but nVidia can do it so I don't see why AMD couldn't. It seems like a pretty basic feature to not have.

If it's anything like regular crossfire on a desktop, you can disable crossfire in the CCC.

What's CCC? Also, does anyone know if a crossfire configuration for gaming is dangerous for a laptop? I'm worried about potential overheating issues.

Yes you can tc. My laptop ( the one in the sig) has asymmetrical crossfire. And it works quite well.

Alot of games render better on card that is true. But all in all, a solid machine for its price.
