Cause why pay extra for something ya don't want? I already have a sound card so I don't want a motherboard with on board sound.
I seems that all the motherboard makers are making new boards with onboard sound, Video, Lan and some even with a modem. I just want a basic motherboard with the basic stuff like Serial port, Parallel port, Usb port, etc. Not all that other stuff.
I have been looking hard and I really want a DDR board but alot of them are coming with onboard sound. I have found a few of the older socket A mother boards that run only SDRAM with no on board sound.
