Both machines are the same except for the motherboards, P 850. Both work great, but if I sell one I can build a new machine. The Abit is a "great overclocker" but they also have a history of dying. I have had both for 3 years so that probably isn't a problem. The Aopen is claimed to be more stable, but I have had no problems with either board. What do you think?? Thanks. R
