Dual Graphics - Connect to MOBO or GPU?

After a few painful hours of research and adjusting some settings in the BIOS, I finally have Dual Graphics enabled. My question now is, should it connect to my monitor via the MOBO or the GPU? I was under the impression that it should connect to my MOBO after the dual graphics feature was enabled, but it only works when connected to the GPU. This may seem like a stupid question with the answer obvious, but I'm just trying to ensure that it's really working.

Pretty good for dual graphics :) lol about the RAM, I was talking more about overclocked RAM, not just more memory. APUs are really the only thing that can profit from overclocked RAM for gaming. Glad you got it working and to satisfactory levels though :)

That was pretty helpful, thank you. My APU is the A10-6800K, which has Radeon HD 8670D Graphics, whereas my GPU is Radeon HD 6570, so I guess I just need to figure which is the better one to plug into.

That it does, but it also states:

However, to be more accurate, we recommend that you plug your monitor into the AMD Radeon™ graphics with the higher model number. If that is your APU, plug into the motherboard, if it is your discrete graphics card, plug into that.

I suppose I could just leave it plugged into the GPU irregardless, but again, any suggestions on what benchmark to use?

I'm not sure there will be an difference in the index with dual graphics enabled and then disabled, but I'll take a look and get back to you.

Sweet, thanks, I'll try that and see if there's any difference. That should be able to tell me whether or not the dual graphics are working. I'll get back to you on that.

Ran the Unigine Heaven Benchmark at High with no tessellation and got a score of 292 connected to the GPU as opposed to the MOBO, which got a score of 269. Altogether, not really impressive. I notice my CPU is getting hot though, so I should probably invest in a different heat sink. Would that help with performance?
 
Well you gotta test it against the performance with dual graphics disabled to see performance changes. Heaven is also very, very strenuous lol

And the CPU is getting hot(ter) because it had the CPU running alongside the fully loaded GPU core inside as well. A new CPU cooler would help you overclock if you want to do that (if your motherboard supports it), so it would help performance.

What would really help your APU is faster RAM, that would help performance. You can try overclocking the RAM as well if your motherboard supports it.

If you're going to spend money upgrading though, I would save a little bit and get a nice GPU :)

I think it was 6.1 or 6.3? I'm not sure, I'm away from the PC at work right now.

Yeah, I'm thinking I should have picked up the 6670 instead since I wanted the dual graphics. It's got a pretty 8 GB of RAM sitting inside of it now, but a second stick wouldn't hurt, and I think I'll get a different heat sink and thermal paste just to be safe. It runs most of my games fairly decently in High to Ultra High settings like Skyrim, so I'm not too worried at this point - just trying to fine tune it. The CCC let's me play with the overclock settings, so I'll tinker with those later.

Sir How did you Dual graphics yours?
I have this specs:

> Mobo: MSI-A58M-E33
> CPU: A10-7850K
> GPU: PowerColor R7 250 1GB DDR5
> RAM: Corsair Vengeance 1X8GB DDR3 1866MHZ

Why I Can't do the dual Graphics thing? I almost do all the changes I can do at the settings, IGD >> Dual Graphics >> 1GB etc..
