Several years ago, I built my own PC which has served me admirably. However, as the usefulness for my system wears thin, I realize it is time to upgrade to bigger and better things. When I built my system, AGP was all the rage, and Pentium 4 was the best you could buy. Of course, this has changed. While I understand the basics of PC building, I'm a bit intimidated by the new technologies out there. I'm sure with the right resources I could get up to speed quickly, but I'm also wondering if it would be cheaper to just flat out buy a system with the way the economy is currently...I can imagine systems might be cheap these days.
