Today I bought a second 7870. Once I got it installed, removed drivers and reinstalled, I started testing. Skyrim (tons of textures and graphical enhancements installed) Age of Conan Borderlands 2 I tried drivers: 12.8 12.11beta 12.10 all with the same result. Skyrim -- exactly the same performance whether or not CF was active (Both with and without CAP) Age of Conan -- Dramatic reduction in performance with CF enabled, even with the CAP. ~50% loss in framerate. Borderlands 2 - *see skyrim This is all taking into effect that I double and triple checked all the connections, looked into gpu-z which reported both as active and at 8x/8x, and removing drivers/doing proper resets. So I am totally stumped -- I had great experiences with 3870CF and 4870CF, Im probably going to end up returning it at this rate, but I thought Id check to see if anyone has any ideas regarding this seemingly common problem.
