hi, I have been running my pc with just the APU graphics alone for a few days (AMD A6 6400k) my new graphics card came today and I installed it with the drivers and enable crossfire and I can confirm the dual graphics is working (Radeon 8470D + Radeon HD 6570) but since ive installed the graphics card it has decreased my fps when playing world of Warcraft.

yeah im running the game in directx11, and I have the latest drivers. device manager is saying it recognises both the APU intergrated graphics and the radeon 6570 together, and in the amd driver control panel its set onto dual graphics and its all fully working. the only problem is that when playing wow my fps has decreased is there nothing I can do?

wow, I would have expected the ram bandwidth to actually bottleneck the APUs performance badly enough for the 6570 to be faster. Just out of curiosity, what ram are you using? I've read some test showing quite nice performance scaling with ram speeds...
