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

Not likely. If you had the DDR5 version of the 6570, it would probably outperform the ddr5 6670 by a little.

I don't know what you're asking in the 4th question. Underclocking is something you do with the CPU, or the frequency of the RAM, not the amount pf RAM. There is no such thing as "underclocking to 512mb"

Assuming you mean lowering the amount of RAM allocated to the on-die, yes that would *probably* help. I can't tell you for sure. I haven't seen your issue in any of the APU systems I've made, though I don't use 32-bit OS's in them.

I meant lowering the gpu's memory size for it not to affect the ram that much and still make use of dual graphics since the total graphics memory size would become 1gb from 2 gpus
with 512 mb each

Wait you're saying a 6570 sold as 1 gb can't be configured to 512 mb in the Bios?

I don't know. I've never attempted to lower the available amount of memory on a dedicated card.

oh, forgot to mention - not sure if it's true with dual graphics ,but generally when you crossfire two cards with different amounts of memory (when it works), the card with more memory automatically cordons off the excess memory to match the card with less.
