1333mhz RAM won't bottleneck that, you might see some difference in synthetic benchies but it should make no difference in a normal game.

So if i understand right this means that both cpus are running at all time but when it needs more fps or power it turns the 2 cpu on???

You can configure Catalyst™ Control Center to automatically set Render (secondary) GPUs in an AMD CrossFireX configuration to a low-power state when they are not in use. To enable this power saving feature, select the Disable AMD CrossFireX Power Settings option.

if you have CrossfireX enabled in CCC both of your GPU cores are working in every game/application that supports them.

If you turn CFX off in the CCC all programs will only utilize one core.

Yes, when your cruising along normally it's like running one downclocked AMD 6970 and where crossfire games are enabled that second GPU kicks in and starts running as two cards on one pcb.

Well it's only occupying one PCIe slot therefor it's a single card technically. That's why it's running better when you have crossfire off.

I've never owned a dual gpu but I'd imagine it's automatic where crossfire is enabled in games that the full potential of your card kids in. CCC is only going to see each PCIe slot that has a card in it.
