I did a clean and reinstall of 10.5a drivers and 10.8a Profile apps. Got very nice gains in BC2. Hardly touched 100fps, now averaging over 100fps. Did not run any benches as I only care about in game performance. Seeing crossfire improvments across a few of my other games as well. Definetly worth trying out that 10.8a CAP. If your a 4870x2 user dont go any higher than the 10.5a on the display driver so you dont loose a core. Worth a shot X2 users if 10.8 drivers are not working for you, plus you gain in crossfire.
