Hey, Voyd, the AMD athlon 550 is a good processor to choose: it's not overpriced, and mine has been working great. I'm not sure what m/b to recommend, having only tried the FIC SD-11. Once I had gotten everything set up right with Windows98SE (it took a few tries), the system has been stable. There may be better m/b's out there with more custom configuration options than the SD-11 gives you.
