ive recently built a new gaming pc. First i had one hd 6870 and now ive got crossfire. My question is, do i need to install graphics drivers for both graphics cards to run crossfire ? Anything else i need to know about crossfire ?
Yes, they both need drivers to run. You'll want to uninstall the AMD Catalyst Drivers, then reboot the system and reinstall the Drivers. Afterwards, enable Crossfire mode within the Catalyst software.
