1333 mhz vs 1600 mhz

Hi. I just put together a system, here are the relevant parts.

i7-2600
2x4GB G.SKILL ram 1600
asus p8 h670m evo mobo

The thing to notice is that the mobo supports max 1333mhz ram (am I wrong?).
My question is whether it's worth it to upgrade the mobo to something that supports 1600mhz ram (will I notice a difference if I'm doing long numerical calculations in c++). Or should I get ram rated at 1333. Or should I leave things as they are? Opinions would be great.

Edit: I just talked to a guy at a computer store. He says that my mobo should be able to support 1600 mhz ram if I overclock. Is this true?

    High End Memory Is Not Worth The Money

    The results are obvious: going from one memory speed to the next, e.g. from DDR3-1066 to 1333, does not provide major benefits. Even the replacement of slow DDR3-800 RAM by DDR3-1600 memory will mostly yield disappointing results. While the performance advantage is measurable, it is never noticeable.

    Of course this is a little late and the poster has probably found his answers eslewhere. But this does benefit me, as I just learned that I don't have to spend money on 1600 ram and a mobo that supports it.

    No, it's not. H67 boards cannot go above 1333 RAM speed.
