Hey all, just built my new computer (gaming primarily), including one stick of 8gb crucial ballistix ram @1600. I was told at microcenter that A) I really should have at least 2 sticks of ram, even though it is already 8gigs. and B) The other module really should be the same size (8gb) as well as speed, etc.

Is that really true? 1) I need at least two ram modules? If so, do they really have to both be 8gb? I would rather same the money and just get a 2gig one. Thanks for the help.
