I'd go with the first set of ram, cause it's a proven company....the 2nd set is new to me, but they got a pretty decent rating among all of their ramsticks and have nice low CAS latencies...
for the motherboards it's a tradeoff....
with the ecs you're getting the 590 chipset, the nice backpanel cpu vent, and the extra goodies, like the esata cable, the crossover cable, the beautiful top hat flash, the nice short sata cables, the esata bracket, and the front bracket for more front usbs....
with the asus you're getting the passive cooling heatsink (which is supersexinice), the stereo array microphone (used to autocalculate/autosetup a room for surround sound, plus a high quality microphone), asus's pretty good support w/ loads of bios updates, and the stability of the 570 chipset.
they're both good boards, and basically come down to how much money you wanna spend and how much noise you like (those fans aren't silent, yaknow
) If you want to in the future, you can spring money for a passive chipset cooler though....
