>that runs at speed up to par with the slowest DDR4 but with DDR3 latency, it is very awesome.

AFAIK ddr4 having higher latency than ddr3 is a myth. It has a higher cl number, but that's measured in cycles, so the higher cl number of ddr4 is compensated by its higher clocks. The actual latency (measured in nanoseconds) is about the same, or slightly lower in ddr4 than ddr3.

I think that's what he's saying, that if the latency is equivalent on best ddr3 and lowest ddr4 and ddr3 is cheaper or you already own it maybe better to wait.
