Question Problems with AMD dual graphics

Have bought a new laptop with AMD Quad-Core A10-5745M and 8670m.
One problem I have is that I get better performance in games when I set the game to Power Saving in CCC than in High Performance ..
I have checked with MSI Afterburner. And with Power Saving the GPU clock stays at 300MHz, at High Performance it goes to 975Mhz. Nevertheless, it performs better in Power Saving ...
I've tried putting all settings in CCC and Windows Power setttings to use the most power (high performance).
Have also seen in MSI Afterburner that the 8670m card is listed as GPU 1-5 and the integrated GPU 6 When I look at the MSI Hardware Monitor during gaming GPU 1 stays at 0% GPU usage ...

And also no difference in games if I turn off dual graphics. It performs the same with just APU, as with APU + GPU...

*Have looked around for many hours searching the net and tried a lot, disabled ULPS, but nothing helps ...

Anyone have an idea?

I've also found that it's best to stick with the manufacturer's latest drivers especially when it comes to the power saving / Dual GFX features.

Be aware that MSI's internal power saving feature takes precedent over the AMD driver. This actually happens with NVIDIA as well.

As a result, you will see any power plan inputs done in CCC throw the driver -> MSI application handoff into "we're confused!!" territory.

I have tried many different drivers. Tried the stock machine when i bought it. Came with windows 8 driver 13.4. Then I upgraded to win 8.1, and downloaded the official driver from HP for 8.1. And also tried with the latest 14.4 driver normal and modified (downloaded from guru3d). All drivers yield the same result.
Got one answer another place that the onboard APU has the better memory bandwith that the 8670m, and that could be why the results are the same with dual graphics turned on or of.

I had the same results before using/installing the MSI Afterburner app, so it hasn't changed the results.

have tested Heaven benchmark and Bioshock Infinite, and in both instances playing the game in Power Saving (just jusing APU) give 10-15% more FPS.
Think I will send this back and use a bit more money on an Nvidia system with a beafier GPU. GTX 760, it isn't that much more..

thanks for your feedback, appreciated :)
