Hello Guys
I borrowed this accnt to ask questions from you more knowledgeable guys.

-Firstly,I'm curious if an hd 6570 1gb ddr3 on dual graphics with an A8-5600K would amount or (hopefully) surpass the performance of a 6670 1gb ddr5
.
-Secondly, I'm using a Windows 7 32-bit OS and installed/usable RAM as displayed in the Computer Properties is 4GB/2.22GB but everytime I increase the integrated GPU memory size in the Bios the Installed/usable RAM is affected. Is this normal with 32-bit systems because I read that other 32-bit systems usually have 3.75 GB usable?

-Thirdly,does having 4GB of RAM installed but with only 1.22 GB usable ,after I will install the 6570(haven't installed ,I'm still watching videos regrading this), affect gaming negatively?

-Lastly, if the 1.22GB usable will affect gaming negatively, will changing the settings in Bios and Dual graphics a 6570 underclocked to 512 mb and a 512 mb 7560D(iGPU) with 2.45 GB usable be the same with hd 6570 1gb + 7560D 768 MB?

I know its a lot of questions and I hope you'll have time to read. Any help is much appreciated. :D

1. In the best cases will give you like 20% perfomance gains maybe less, gddr3 it´s a terrible bottleneck and that´s not going to happen in all games.

2. The integrated graphics use your board ram as graphics memory so that´s why it´s affected, a 32 bits OS can´t use more than 3.75 GB of ram that ram that you can´t use it´s maybe being used by the integrated graphics card, try to make the pci-e slot gpu as the primary one so it won´t use your ram.

3. No it won´t, in fact your gaming experience will improve, if it isn´t your igpu that it´s using it then yes it will.(see above answers).

4. Just let them use the memory that comes with the hd 6570, 1GB it´s plenty for that cards and you will have more available ram for multitasking and...

Well with my experience with apu's the dual graphics mode just slows down your gaming performance and the 6570 is barely slower than the 6670. your better off just using the 6570 and not touching integrated graphics now. once you install the 6570 you will have all your ram useable again due to the integrated not being in use, not using any of your ram.
