I have recently acquired my friend's old i7-920 and I'd like to build around it. I haven't done a build in probably 8 years or so, so I am looking for some help. I'm not a power user, a few games here and there (Diablo 3 in May) maybe a couple others. I'm trying to keep the cost down, but leave room for later upgrades. What would be a good budget build to get me started?
