amd crossfire?

[heartofgold]

I recently purchased this laptop:

I have also read about something called crossfire, which seems to me like utilizing both gpus (dedicated and integrated in this case) to provide a slight boost in gfx permorance. Is that possible with this laptop, or am I simply mistaken on how this works?

Also, is the dual graphics mode what I should always have it in when I play games? Are there any downsides to running in crossfire all the time?

And one more question: I've done some research on laptops that have dedicated graphics. Is the dedicated gpu something that will kick in automatically for more demanding games, or do I have to manually enable this card somehow?

These are not settings you need to enable. If your laptop was designed with a crossfire setup, it's running crossfire. If it was designed with a discrete GPU, it's running off the discrete GPU.

This is not something the user is required to manage.

ok, thank you. I've read in other threads where you have to go into bios and change settings from dynamic to fixed for gpus when notebooks have both dedicated/integrated cards.
