Hi everyone and thanks for your help. Before answering question, please note, I can get the XFX card for $80. My current set up is running as follows: AMD A10-6800K Richland dual graphics with the Sapphire HD 6670 1gb DDR3. Now the one I can purchase is a XFX HD 6670 1gb DDR5 model HD677XZNFC. Now is this graphics card able to combine with APU graphics for dual graphics? Or is it better to crossfire the 2 if possible? If crossfire is possible will it bottleneck with A10, plus will graphics run DDR3 or DDR5 if crossfired? Any help would be appreciated.

As far as I know, for every case of SLI/Crossfire, the card would work on the lowest setting (frequency mainly, at the time NVidia allowed different Memory Sizes card to work on SLI, it would scale the one with the most memory to the size of the one with the lowest), therefore it would work on DDR3 instead of DDR5 - which compromises your performance - and I am not really sure you could dual graphics it with the APU without loosing performance as well...

That's what I'm afraid of. Spending $80 on a graphics card that will just run the same as old one.

Since I do not own an APU system running with Dual Graphics, I cannot guarantee it, I can use what I have read about it.

At this moment, in order to get the best performace you can, you should be looking for a GDDR5 memory VGA... according to the February chart, the one closest to your budget would be the R7 250, ensure that card is the DDR5 model and not the DDR3 one.

It should provide a better gaming experience than what you have at this moment.
