eh.. where's the poll? btw, Opti ViperM rules! (j/k)
there's no point getting KT133 if you can get KT133A.. I sorta don't understand the reason for the poll, if you have to choose certain MB that only use KT133 and another MB that has KT133A, It'll make sense, but the chipset itself has only minute difference. but then the question will be on which MB not which chipset.
