I just got my KT7, and I love it so far. Minor problem on first boot up you should watch, you need to go in and auto-detect ALL IDE devices EVEN if they are displayed correctly in the main screen. Also, there are less problems if you do a clean re-install of Windows, but it can be done without if you clear out your hardware profile before booting on the new mobo. Oh and also make sure to install the VIA 4in1 driver before you restart Windows for the first time.
(I forgot to enable my CD-ROM drives in the BIOS and I didn't have Win98 copied to the HD so the OS got a little upset. Oops) But it all worked out now.
