So I have a mini itx gaming pc with the a10-6800k apu with a open pci express slot. I want to add a gpu to increase my gaming performance. On the box for the a10 it recommended the 6670 gpu to crossfire but that shit is old now. So I was wondering if I could crossfire with a 2gb hd 7850 Gddr5 256bit because I seen on youtube ppl crossfiring with 7770 which is amazing I just want to go higher. Also how do u crossfire an apu PLZ HELP.
