I have a KT7 with a T-Bird 750. If I got the Duron it would probably be the 700, although you might get lucky with the 600 and get one that clocks to 1Ghz. You never know. It took watercooling to get my T-Bird to 980 Mhz. Then again people are running T-Bird 750s on air at 1100 Mhz. I love the KT7. It is the best motherboard I have owned in a long time. I have had other Abits, Asus, Soyo, FIC and other boards.
