KT7A is a pretty good board. the chipset (KT133A) is a little finicky sometimes. check around to read about some of the hardware incompatabilites as well. the nice thing about this board is that it was/is extremely popular, so many if not all of the problems have been discovered and more or less fixed or solutions are available.
the best source of info on the board i've found is Paul's KT7 FAQ over at viahardware.com. he's got all the drivers, bios', everything. Great source of info on problems and solutions.
