I wouldn't recommend using an LM317 regulator to get the +3.3V. It's not DC-DC in the sense that it is a linear regulator and not a switching type and will generate much more heat as a result. Most boards do use the +3.3V to generate the CPU core voltage and it also appears on the PCI and AGP bus, plus some SDRAM use +3.3V instead of +5V
