I am thinking of upgrading my processor in my computer from an AMD A4-6300 to an A10-8750, which is listed as compatible with my motherboard, but I can not find the A10-8750 for sale anywhere, but it is the one I would like to get, does anyone know wjhy this processor is not for sale right now? And also when replacing my processor will I need an APU or a CPU? I do not understand the difference, I assume I only need a CPU, but I see lots of processors now are APU, which include a video card if I understand correctly? so when I remove the A4-6300 I will remove the video card as well? And if I order an APU it will include a video card? I have not built a computer since 1999, and I don't remember exactly how I did it all. but I remember I had to buy a separate video card back then. But my computer I have now has a HDMI output for video. There should be a big jump in going from an A4-6300 to an A10-8750 correct?
