i would go with gigabyte UD3R won toms award for best value. .has alot of features for less than the asus brand. However they are both good boards..
ditch the enermax PSU and get an quality brand. I use the OCZ stealth xtreme 700watt unit. and I don't experience the whine that some ppl experience with dif brands and models.
for ram I am partial to the mushkin redline enhanced as it fits under my noctua D-14
and has awesome timings at 6-8-6-24 at 1T(N) running 1600Mhz
if you are overclocking, I would strongly recommend an aftermarket heatsink
