Sorry if the post seem a bit negative, but eh....
1: If you bought everything already, then you made a downgrade in the processor department. A side grade at best.
2: No platform supports "quad channel", it is either dual or single with AMD platforms. The only platform that supported higher than dual, was the 1366 you had before (triple channel).
3: Overclocking RAM is not that useful, not in real time performance, not in games. Pick the one with the higher memory and be done with it really.
4: If you would go for the H100i, you wouldn't miss out much on performance if there was a better cooler. It would only be a 2 degree difference, if even that.
So it is better to get 2 dual channel sets than just purchase a quad channel set or just cheaper? I thought the matching pairs would be good so it didn't matter what bank you put them in like my triple channel.
If you would buy a set of four (8gb each) RAM sticks, they will run in dual channel, since that is the highest AMD platform goes.
I never really went for that "matching pair" stuff, it always worked for me, even if they weren't a matching pair (same speeds though, that IS important 
)
