My 6870's have been damn good cards. Not a hiccup from either one. This has been my first Crossfire setup since the dongle days and I gotta say it really has shown me how far AMD has advanced in multi-chip/card technology. Especially with the recent additions in Cat 12.1 allowing for easy Crossfire profile selection.
Solid cards through and through, but I think I'm going to be going back to single card for awhile, because there's a HIS 7970 somewhere on it's way from California with my name on it that will be taking it's place
Now my 6870's will allow two more members of my family to enjoy DX11 sweetness, so they will still live on!
Taking bets on how long it takes me to get that second 7970
