It gives better performance doesn't it? I'm pairing it up with an i5 4670k and a gtx 780 with an ssd so i don't want any bottlenecks. Great motherboard suggestion, I will almost certainly get it
thanks.
Yes it gives better performance on synthetic benchmarks only, the human eye and brain will not spot those tiny differences between RAM speeds of 1600Mhz and 2133Mhz.
I would say get 1600Mhz with CL9 or since you have Haswell i5, get nothing more than 1866Mhz, Haswells do like 1866Mhz
