Hi, I've been offered to purchase an AMD A4 4000 APU and a motherboard that supports 16 DDR3 GB RAM. The problem is that I already own a ATI Radeon HD 6670 DDR5. Will there be a problem if I use my ATI Radeon HD 6670 with an AMD A4 4000 APU? What other AMD CPU can I use with my Graphics card? I've thought about purchasing one without integrated GPU but I'm not sure what my best option is here. I've also read that I can disable the GPU on AMD CPUs, so I've thought about disabling the AMD A4 4000 GPU in order to use my Radeon HD 6670. I'm not sure what my best option is here.
