Will Dual Graphics Work?

So I am getting a computer with the Radeon HD 8570 OEM GPU with the A10-6700 APU. The APU has 8670D integrated graphics. My question is, can I combine the power of my discrete and integrated graphics cards together to increase performance in games?

you can not crossfire but you can disable dual graphics and add a 8750

You can only dual graphics a 6450, 6570 and 6670, with the 7750 having rumors it can work with dual graphics albeit poorly

Oh okay. But which is better, the 8570 or the 8670D integrated GPU. Which will provide more power? The Radeon 8570 has 2GB VRAM.

I have a related question. I'm thinking that enabling the 6750 card in the southbridge in the bios has prevented me from using dual graphics. In the AMD Vision engine the ability to enable dual graphics is grayed out. Two adapters show up. One is the 8670D and the other is the 8670D + 6570 Dual Graphics. How do I get the dual graphics to work? Is it because of what I did in the bios and therefore the DVI cable needs to be connected to the onboard video for this to work?

I'd say it's decided to use only your 6570 as the discreet card, but i don't know, i've never had this problem.

Perhaps try undoing everything you did, and go back into the Vision control center and see again.

I thought of two possible solutions: 1)Force the onboard video in the bios. 2)Remove the discreet video card, restart the system with the DVI connected to onboard video, thus giving the bios no choice but to select onboard video as a display device, then let windows start, shut down, reinstall the video card, then restart with the DVI still connected to onboard video and hope the dual graphics can then be applied in the AMD vision. The second one requires more work but I'm wondering if forcing onboard video in the bios is going to work.

try the first option, it will probably work

I called AMD. They provided the best solution. 1) Go into AMD Vision Engine, disable Dual Graphics in Performance > Dual Graphics. 2)Shut down the machine. Restart after connecting the DVI to the onboard video. 3)In the BIOS enable the IGD Internal Graphics and choose "Auto" as the function underneath. After that windows started properly with video. There was a conflict between what Windows believed to be the correct video adapter and what the BIOS had determined. After that, re-enable dual graphics in the Vision Engine Center. It works nicely now and my WEI score went from 5.6 to 6.7. Not bad at all.

I'm let down by my HDD, which gets a 5.9. CPU gets 7.3 and graphics gets 6.7

The lowest subscore thing is a bad system

I don't really put too much into that overall number. The number favors Windows and that Aero graphics theme. My SSD gives me a 7.9 on that score. The other numbers are perhaps more important but they are values that Microsoft assigns. I have no idea really what they base them upon. When I install some of my processor or graphics intensive programs then I'll know the benefits of what I've built. SSDs have become much less expensive then they ever were. Mine is a Mushkin Advanced Chronos Deluxe 240gb. I got it on sale at Newegg for $159.
