P4 is gonna be a socket 478 (or something like that)
I'm happy with the Asus board I've got (check the sig). FSB settings can be changed by single mhz, should be good for overclocking, but I haven't gotten much into that yet. Went from 100 fsb to 106, and my stupid Sounblaster 16 card started crapping out. I supposed it's time for a better sound card. I think you can lock the PCI speeds as well with this board, but I haven't tried that yet either.
Anyway, the board is rock solid, folds 24/7.
