I'm just wanting some clarity of why this question was closed. It states that the question is "ambiguous, vague, incomplete, or rhetorical and cannot be reasonably answered in its current form", however I feel that the question is pretty clear:
What are the differences?
Why are some motherboard supported of one type?
Is there a way to have both work?
I'm just wanting some clarity of this so that I can write better question further on.
