I tend to be shy about on-board video because of past failures, so I
tend to look for a mobo that provides for a replaceable video card and
would like to have firewire, and DDR 333 -- are you aware of an equally
rf-quiet mobo that has these features, please?
Or must one settle for a little older technology in order to find more
stability and less noise?
Thanks! & 73, doc kd4e
