According to the benchmarks a really low latency 1600 set (think mushkin 6-6-5-18) performers better 2/3 times, including gaming. Actually looking here
the only thing the fast ram did better in was superpi, which doesn't count for anything. Then factor in the that it would cost half the money... It would take a grade A fool to buy this ram. Blindly assuming faster clockrate/more expensive = best performance. I can't stand people that live their life so half-assed.
