If you're just itching to upgrade, got PCI-E. The cards are cheaper since they don't have to add on a bridge chip.
BTX isn't gonna come for a while, even though Intel is pushing it.
All of the future is most likely gonna be PCI-E until the next spec comes out.

I doubt if you would be able to find any BTX mobo for now. (and you will need a special version of Pentium 4 if you indeed have a BTX mobo).
Go PCI-e unless you have a powerful AGP that you have to keep.
