Hi all, With funds low but I really want a computer, I thought of getting a second hand one and building upon that, changing components when I get the extra cash. If I pick up a PC with a Duron Socket A chip, would I be able to swap that for an Athlon (XP?) Socket A chip or maybe up to a Sempron if they are socket A ?! A friend seems to think it would work but I can't believe it would be that easy. Any advice ? Thanks, Richie.
