PCIe is a fact that sound card makers must deal with. If they don't like it they can, as you say, lump it.
The sound card maker with with the most muscle is Creative but even they are small pathetic & insignificant fry when ranged against Intel, ATI, NVidia, AMD etc all of whom have decided that the future is PCIe.
Not sure where this leaves me. Most likely buying a good NF4 system now and waiting an annoying while for a card maker to come up with a product that works properly with it.
A Tyan based system would be overkill/too pricey for me.
