Is it possible that the bench doesn't support Xfire?
Maybe reinstall the one driver, if no help try reing both.
What are your clocks set at?
Is the 6970 in primary slot(top)?
Is your OS up to date?

the bench does support multi gpu and the 6950 is on the primary and the os is up to date should i install the 6970 in primary and install the drivers then reboot and install the 6950 ? or should it work while putting them both and installing the drivers becuase i tried to reinstall the drivers many times and using driver sweeper and there no luck to get directcompute on the 6970

Try uning card drivers, shut down put 6970 in top slot and boot with just that card.
See if GPU-Z DC 5 checked, if it is shut down put 6950 in secondary slot & boot. If OS installs driver for 2nd card automatically and it's ok good if not insall driver manually.
Hopefully it'll work!
