Using a mic

i'm planning on getting a decent quality mic for my pc. maybe a Shure SM58.

i'd like to know if it'd still require some sort of interface software..

or will it work if i just plug it in directly to the mic input of my mobo. (mic -> xlr to 1/4"-> 1/4" to 1/8" -> mic input)

Is it 6.5mm?

If it is, you're fucked.

Either get a receiver that outputs to SPDIF get a motherboard/soundcard that has SPDIF in.

Or get a 6.5mm recorder to USB from Sam Ash/Guitar Center; the same ones used for guitar/bass recordings

I have a Logitech Rockband mic; it is the godliest thing I have ever used in my life.

do you have to stay close to the rockband mic for it to pick up your voice clearly? around how far from the mic are you seated?
