you just described the SiS chipset, ecs makes the k7s5a with it and it's probably the best SiS based motherboard out right now. you can look back and only find very few posts with problems about that board, but even those are usually just settings or something. i ordered one yesterday should get it by wed. though i've heard that the amd 761 is good. and if you want to chance it you could wait for the kt266a and see how it is?
ewww, put that thing away, you're in public!
