Okay so I know some about computers and I thought I had in mind exactly my dream computer I was going to start building but then I tried to find a way to make it affordable I thought of things I could later add, now I have an x99 deluxe ii asus mother board which runs on quad channel as everyone knows, the one thing I'm curious about is can I put in two sticks of ram into it and later add another two just so I can get some part of this up and running or do I need all four right now?
