Getting a ddr3 board now DOESN'T make it futureproof. As with all new formats, improvements will be made to make it better and faster. This means that the northbridge and the chipsets of the future will be made to tailor the changes. If you get a ddr3 board now, you stuck with that chipset. Newer chipsets which works better with ddr3 would not be on your board in the future because it is not made yet. This is why a ddr3 board isn't futureproof.
