DDR-333 memory in DDR-266 motherboard?

I have a DDR266 motherboard. Since DDR333 is the same price
of DDR266 here, may I buy DDR333 memory and use in my board?
So I'd save money/trouble in a future mobo upgrade.

Also, wouldn't it work better anyway? (say, if I tried to
overclock my current board)

Thanks
