  • If you could include some pictures or something just to make your answer more detailed in appearance. You could also mention the pin and grooves for each the CPU and board. Another good point would be that PGA is AMD and LGA is Intel. This input is only given because for some reason someone gave you a downvote, even though your answer is correct.
