Provided you have a decent, name brand power supply and good RAM (Crucial works best) the K7S5A will not let you down. It's an outstanding board for the money. Heck, the money you save with it over other boards you can use to buy quality RAM and a quality PSU.
Just don't look to do any overclocking with this board. However, there is an overclocker's hacked BIOS available in the forms at www.ocworkbench.com
That site is also an excellent source of info on the K7S5A. It's become quite a cult classic among its faithful users.
