I would go with the professional board. It has the 16+8 power phase and a second pcie 3.0 lane that might come in handy down the road. Of the 2 choices you gave I would go with the corsair because of the lower latency. I would, if it were me, take a look at the G-Skill 2133 memory. Latency goes up but I like the speed boost myself.
Don't be fooled by the 1333 - 1600Mhz you see on the web site. Those are official specs and they won't guarantee memory that is overclocked and 2133 is an overclock. If you look at the specs for the motherboard it tells you that these DDR3 2800+(OC)/2400(OC)/2133(OC)/1866(OC)/ 1600/1333/1066 are the supported memory modules so as long as you pick something off their QVL for your board you will get those speeds. ^ you notice the OC OverClock
