Your mobo suppose to set the PCI bus between 31 - 41, so sound card should not be a problem. My SB!live value stand up to 41.
As for vid card, Geforce should withstand the most FSB.
What is the model of your mobo, this new mobo should be able to set the AGP ratio to 1/2 at 133Mhz. Make sure is not the ViaKT133 chipset, they can't go more than 110 on FSB.
