Help! I have a a ATI HD5850 currently in my system, and have just got a 6870.

I added the 6870 planning to running that as a separate miner in the same rig. However the 6870 isnt being picked up by guiminer nor is GPU-Z showing that the card is OpenCL enabled. Very confused!

I knew I couldnt crossfire them, but thought they would run side by side loll

Help if you can! would love to make this work!
