Here's a quote from the last review listed: "...it is comforting to know there is support for the latest and greatest features and technology ( including the Barton-cored Athlon XP ) and the platform has proven to be solid as a rock. Plugging in a next-generation AGP8X graphics card, this consumer is sure to be gaming with a state of the art system. In the end, I find it hard to imagine anyone going wrong with this motherboard. Aside from the meager overclocking potential, this motherboard exhibits a stellar combination of price, performance, and functionality that consumers have only dreamt of until now. "

I just picked this puppy up last week and I love it. I'm still finding new ways that I can take advantage of all its features.
