I trash em from personal experience, lol.
I mean, why take the risk?....my K7S5A didnt like a power supply that was fine on other boards...and then there was the "hmm, why doesnt the driver FROM the ecs site work" factor...then on my other ECS board, a K7ama I think....they dont even have new IDE drivers etc after several years...sad.
Sometimes there is a reason why certain boards tend to be sold mostly thru 'deals' and "promos"...
I guess if you "happen to get a good one" youre ok, lol.
