I do not understand these questions.....
If you are using old hardware that you know nothing (or not enough) about and you have questions, these great forums can help you.
But if you are building computers and every time you have to make a basic choice to which parts you use you need to ask......comon.
No one here knows what you want to do with it, so only you can make the choices. You know what the hardware is capable of.
I'm still waiting for the first person that comes to ask what sweater to wear when they are building computers.
