...probably going to be a new CPU or a new CPU and mobo if I decide to go AMD (most likely). If I go just the CPU it'll be an Intel PIII 850E to overclock. If I go AMD I'll probably wait a few months for the prices to fall of the 133 core cpus and DDR mobos. Motherboard makers (Abit all the way) and chipset vendors should have any bugs worked out of their DDR parts by then too.
